Passkeys vs Passwords vs 2FA: 93% Success Rate

Security teams spent the last few years telling everyone to turn on two-factor authentication. In 2026, the advice has quietly changed again: skip the password and the extra step, and log in with a passkey instead. The FIDO Alliance now counts 5 billion passkeys in active use worldwide, and 90% of consumers say they at least recognize the term. Passwords have not disappeared, though, and SMS codes, authenticator apps, and push notifications still guard the majority of corporate logins. This comparison lines up passkeys vs passwords vs 2FA using benchmark data from FIDO’s Passkey Index, NIST’s current authentication guidance, and real deployment numbers from companies running passkeys at scale, so you can figure out which one actually belongs on your login screen.

The short version: passkeys win on security and speed in nearly every published benchmark, traditional 2FA still fills gaps passkeys cannot reach yet, and plain passwords with no second factor are the option every report below says to retire. The data explains why, and where each method still makes sense in mid-2026.

What makes this comparison different from the passkey explainers that circulated in 2023 and 2024 is that there is finally real production data to argue from. Early passkey coverage leaned on vendor promises and lab demonstrations. The numbers in this piece come from live sign-in logs at some of the largest platforms on the internet, a government cybersecurity agency’s own testing, and the body that writes federal authentication standards. That is a very different evidence base than “passkeys should be more secure in theory,” and it changes how confidently a security team can actually recommend one method over another.

Passkeys vs Passwords vs 2FA at a Glance

Before the deep dive, here is the fast answer. A passkey replaces the password entirely, using a device-bound cryptographic key pair unlocked by a fingerprint, face scan, or PIN. A password paired with 2FA keeps the password as the first factor and adds a second check, usually a text message or a six-digit code from an app. Passwords alone rely on a single shared secret that a user has to remember and a server has to store.

The FIDO Alliance’s Passkey Index, built from sign-in data at Amazon, Google, Microsoft, PayPal, Target, TikTok, and other large platforms, found that 36% of accounts already had a passkey enrolled by late 2025, and passkey sign-ins succeeded 93% of the time versus 63% for older methods. That gap is the whole argument for passkeys in one statistic: fewer failed logins, fewer support tickets, and fewer chances for an attacker to intercept a code in transit.

Attribute	Passkeys	Passwords Alone	Passwords + 2FA
Phishing resistant	Yes, by design	No	Partial (SMS/app codes can be relayed)
Requires memorization	No	Yes	Yes (password) + device access
Vulnerable to credential stuffing	No (no shared secret to steal)	Yes	Reduced but not eliminated
Vulnerable to SIM-swap attacks	No	N/A	Yes, if SMS is the second factor
Works without internet access	Yes (local biometric/PIN unlock)	Yes	Depends on method (SMS needs signal)
Cross-device sync	Yes, via platform cloud (iCloud Keychain, Google Password Manager, etc.)	Only with a password manager	Varies by app
Average sign-in time	8.5 seconds	Varies, often 15-20 seconds	31.2 seconds
Setup complexity for end users	Low (biometric prompt)	Low	Medium (app install or phone number)
Account recovery method	Backup passkey or platform account recovery	Email/SMS reset link	Backup codes or admin reset
NIST SP 800-63B-4 status	Preferred, phishing-resistant authenticator	Permitted but discouraged alone	SMS OTP is a “restricted authenticator”
Biometric option	Built in	None	Only if the authenticator app supports it
Typical cost to the end user	$0 on existing devices	$0	$0-$98 if a hardware key is used

What Is a Passkey, Really?

A passkey is a credential built on the FIDO2 and WebAuthn standards. When a user creates one, the device generates a public-private key pair. The private key never leaves the device or its secure enclave, while the public key goes to the website or app. Logging in means the server sends a challenge, the device signs it with the private key after the user unlocks it with a fingerprint, face scan, or PIN, and the server verifies the signature. No shared secret ever crosses the network, which is exactly why passkeys resist phishing: there is nothing for a fake login page to capture and reuse.

The FIDO Alliance describes passkeys as phishing-resistant by design and positions them as a direct replacement for the password-plus-SMS-OTP flow that has dominated consumer logins for the past decade. Most passkeys today are “synced” passkeys, meaning Apple, Google, or Microsoft backs them up to an encrypted cloud keychain so a new phone can pick up where an old one left off. Enterprises that need a credential tied to one specific piece of hardware can still choose device-bound passkeys, often stored on a physical security key.

For developers, feature-detecting passkey support before showing a passwordless option is a one-line check against the browser’s WebAuthn API:

if (window.PublicKeyCredential &&
    PublicKeyCredential.isConditionalMediationAvailable) {
  const supportsPasskeyAutofill =
    await PublicKeyCredential.isConditionalMediationAvailable();
  if (supportsPasskeyAutofill) {
    // Safe to enable passkey autofill on the login form
  }
}

That single check is why passkey rollouts have moved faster than most past authentication upgrades. There is no new client software to distribute. The capability already ships in Chrome, Safari, Edge, and Firefox, and in iOS, Android, Windows, and macOS.

Synced passkeys vs device-bound passkeys

The distinction between synced and device-bound passkeys matters more than most quick explainers admit. A synced passkey lives inside a platform’s encrypted keychain, Apple’s iCloud Keychain, Google Password Manager, or a third-party password manager that supports passkey storage, and rides along whenever a user signs into that ecosystem on a new device. That is convenient for consumers switching phones, but it also means the passkey’s security now partly depends on the strength of the account protecting that cloud keychain in the first place.

A device-bound passkey, by contrast, never leaves the piece of hardware that generated it, typically a YubiKey or similar security key, or a device’s own secure enclave with no cloud backup enabled. It cannot be copied, exported, or synced anywhere, which is exactly why regulated industries and high-security enterprise roles tend to prefer it despite the added friction of carrying a physical key. The tradeoff is recovery: lose a device-bound passkey’s hardware and there is no cloud copy to fall back on, only whatever backup authenticator the organization enrolled ahead of time.

Where Passwords and Traditional 2FA Still Stand in 2026

Passwords are not going away this year or next. Legacy systems, internal tools built before WebAuthn existed, and a long tail of smaller websites still expect a username and a string of characters. Traditional 2FA, meanwhile, means one of three things in practice: an SMS one-time code, a six-digit code from an authenticator app using the TOTP standard, or a push notification a user approves on a second device.

SMS OTP is the weakest of the three, and regulators have started saying so directly. NIST’s current Digital Identity Guidelines FAQ states that “authenticators leveraging the public switched telephone network, including phone- and Short Message Service (SMS)-based one-time passwords (OTPs) are restricted.” That “restricted authenticator” label is new to the latest revision of NIST Special Publication 800-63B and comes with extra obligations for any organization that keeps using SMS codes as a primary second factor. Authenticator apps fare better since the code never travels over the phone network, but both approaches still depend on a password as the first factor, and passwords remain the piece a phishing page can trick a user into typing.

None of that makes 2FA useless. A stolen password paired with a working second factor still stops the overwhelming majority of automated credential-stuffing attempts, and authenticator-app codes remain a reasonable fallback for the accounts and devices that cannot yet do passkeys. The honest framing for 2026 is that 2FA is a strong bridge technology, not the finish line.

Security Showdown: Phishing Resistance and Regulatory Guidance

Phishing resistance is the single biggest differentiator in this comparison. A password can be typed into a fake site. An SMS code can be relayed in real time by an attacker running a proxy login page. A passkey cannot be phished this way because the cryptographic exchange is bound to the exact website domain that created it, so a lookalike domain simply cannot request a valid signature.

The cloud communications company Twilio put it plainly in its own guidance for developers: “Compared to passwords, passkeys are more resistant to credential stuffing and other remote attacks and generally offer consumers and corporations greater security.” Government cybersecurity agencies have reached the same conclusion independently. The UK’s National Cyber Security Centre found that “FIDO2 credentials including passkeys are more secure than traditional multifactor authentication against all common attacks, and at all stages of the credential lifecycle.” That last point matters. The NCSC is not just saying passkeys are harder to steal at login, it is saying they hold up better through enrollment, daily use, and recovery too.

There is a common misconception worth clearing up here. Passkeys are sometimes described as “just 2FA built into one step,” but that undersells how they work. As the passkey-focused security publisher Corbado explains, “passkeys fulfill the security goals of 2FA without requiring two separate steps.” A passkey combines something the user has (the device and its private key) with something the user is or knows (the biometric or PIN that unlocks it), which is the same two-factor principle regulators require under frameworks like the EU’s PSD2, just collapsed into a single tap instead of a password followed by a code.

Where Passkeys Can Still Go Wrong

None of the reporting above means passkeys are immune to every attack, and a fair comparison has to say so. The most discussed weak point is account recovery. If a synced passkey lives inside a cloud keychain, then the security of that passkey is only as strong as the account protecting the keychain itself. An attacker who takes over an Apple ID, Google Account, or Microsoft account through a separate vector, a recovery email compromise, for instance, can potentially reach every passkey synced to it. That is not a flaw in the FIDO2 cryptography. It is a reminder that passkeys move the security perimeter rather than eliminating it.

Malware on an already-compromised device is a second gap. A passkey’s private key cannot be phished remotely, but if an attacker already has full control of a user’s unlocked phone or laptop through separate malware, they may be able to trigger authentication ceremonies directly on that device. Passkeys raise the bar for remote, at-scale phishing campaigns significantly. They do not make a fully compromised endpoint safe.

Downgrade attacks are a third practical concern for any site that still offers a password fallback next to passkey login. If a service allows either method, an attacker can simply target the weaker one, meaning a passkey rollout only delivers its full security benefit once the password option is actually retired for that account, not merely offered alongside a shinier alternative. That is precisely why FIDO’s own numbers show a gap between the 36% of accounts with a passkey enrolled and the smaller 26% of sign-ins that actually use one: as long as the password door stays unlocked, some users and some attackers will keep walking through it.

Benchmarks: Login Speed, Success Rate, and Help Desk Costs

Security arguments convince security teams. Speed and reliability numbers convince everyone else, and this is where the passkeys vs passwords vs 2FA debate gets concrete. FIDO’s Passkey Index pulled sign-in telemetry directly from nine major platforms rather than relying on a survey, which makes it one of the more credible datasets in this space.

Metric	Passkeys	Traditional Methods	Source
Average sign-in time	8.5 seconds	31.2 seconds	FIDO Passkey Index, 2025
Sign-in success rate	93%	63%	FIDO Passkey Index, 2025
Login-related help desk incidents	Baseline	81% higher	FIDO Passkey Index, 2025
Password reset tickets after passkey rollout	35% fewer	Baseline	FIDO State of Passkeys 2026
Phishing-related incidents after passkey rollout	32% fewer	Baseline	FIDO State of Passkeys 2026
Accounts with the method enrolled	36%	64%	FIDO Passkey Index, 2025
Share of all sign-ins	26%	74%	FIDO Passkey Index, 2025

Read the last two rows together and the adoption curve becomes clear. Passkeys are enrolled on more than a third of accounts but still handle only about a quarter of sign-ins, which means plenty of users set one up and then default back to old habits when a site does not prompt them. That gap is a user-experience problem, not a security problem, and it is the main thing standing between passkeys and majority adoption.

On the enterprise side, organizations that have deployed passkeys for employees report 47% improved confidence in their security posture, 45% faster employee logins, and 43% higher satisfaction with IT, according to FIDO’s State of Passkeys 2026 report, published on World Passkey Day, May 7, 2026. Those numbers come from IT and security leaders describing their own deployments, which is a softer data source than the Passkey Index’s raw sign-in logs, but the direction matches across every report cited here.

For a CISO building a budget case, the help desk numbers tend to land harder than the security argument alone, if only because they translate directly into headcount and ticket-queue math a finance team can verify independently. An 81% reduction in login-related help desk incidents is not a security metric dressed up as a cost metric. It is a straightforward operating-expense reduction that happens to come from a security investment, which is a rare combination and one reason passkey rollouts have found executive sponsorship faster than most past authentication upgrades did.

Adoption in 2026: Who Is Actually Using Passkeys

Adoption has moved faster over the past year than most authentication upgrades typically do. FIDO’s State of Passkeys 2026 report puts consumer awareness at 90% are aware of passkeys, and 75% of consumers now have enabled a passkey on at least one account. Roughly half of consumers, 28% say they use a passkey regularly whenever one is offered.

Website support has grown alongside consumer awareness. FIDO’s 2025 World Password Day research found that 48% of the world’s top 100 websites had already integrated passkey support, and that figure has almost certainly climbed further through 2026 given how many large platforms have since made passkeys a default sign-in option rather than an opt-in extra.

Enterprise workforce adoption

On the workforce side, 87% of surveyed U.S. and UK organizations were deploying or actively rolling out passkeys for employee sign-in as of early 2025, up 14 percentage points from the prior survey. By 2026, FIDO’s newer data shows 68% of organizations deploying, piloting, or rolling out passkeys, with 28% reporting they have reached fully passwordless authentication for their entire workforce. Separately, Descope’s State of Customer Identity research found that 45% of organizations have deployed passkeys in at least one customer-facing application, with another 27% actively expanding their rollout.

The gap between “87% deploying” in one survey and “68% deploying” in another is not necessarily a contradiction. Different surveys sample different company sizes, industries, and countries, and “deploying” can mean anything from a pilot with 50 employees to a company-wide mandate. Treat any single adoption percentage as directional rather than exact, and look at the trend across reports instead of any one number in isolation.

What is consistent across every survey cited here is the direction of travel, not just the size of the number. Every report published in 2026 shows higher awareness, higher enrollment, and higher regular usage than the equivalent report from 2025. None shows adoption flattening or reversing. For a security technology that depends heavily on network effects, meaning it gets more useful to everyone as more services support it, a consistent upward trend across independent surveys is arguably more informative than any single snapshot statistic.

Pricing: What Passwordless Actually Costs

One of the more persuasive arguments for passkeys is that the core technology is free. Windows Hello, Apple’s Face ID and Touch ID, and Android’s biometric unlock are already built into the devices most users own, and platform passkey support adds no extra line item beyond the hardware itself. Costs enter the picture when an organization needs enterprise identity management on top of that, or when it wants hardware security keys for employees whose phones are not an acceptable authenticator.

Option	Price	Billing Model	Source
Platform passkeys (Windows Hello, Face ID, Android biometrics)	$0	Included with the device	Platform vendors

Okta Workforce Identity	Quote-based	Contact sales, no public list price	okta.com
Ping Identity	Quote-based	Contact sales, no public list price	pingidentity.com

Two vendors on that list, Okta and Ping Identity, do not publish list pricing for their workforce identity products at all, which is standard practice across most enterprise identity platforms. Budgeting for those requires an actual sales conversation rather than a published rate card, so treat any per-seat figure you see quoted for them secondhand with caution unless it comes directly from a current vendor quote.

The real cost comparison rarely shows up in a price sheet anyway. It shows up in the help desk numbers from the benchmarks section above: 81% fewer login-related support incidents and 35% fewer password reset tickets after a passkey rollout. For any IT team running a support desk sized around password resets, that reduction alone can offset the cost of licensing an identity platform within a year or two.

Real-World Examples: Companies Making the Switch

The FIDO Passkey Index is built on production sign-in data from nine companies that agreed to share aggregated numbers: Amazon, Google, LY Corporation, Mercari, Microsoft, NTT DOCOMO, PayPal, Target, and TikTok. That list alone covers e-commerce, cloud services, social media, and payments, which is a wide enough spread to say passkeys are no longer a niche feature limited to one industry.

These are not pilot programs buried in a lab. Every platform on that list processes billions of login attempts a year, which means the 93% success rate and 8.5-second average sign-in time cited earlier reflect real production traffic under real attack conditions, not a controlled test environment. A few examples worth calling out individually:

• Google made passkeys the default sign-in suggestion for personal accounts, steering users toward them instead of a typed password whenever the option is available on a supported device.
• Microsoft followed with its own default-passkey push for Microsoft consumer accounts, aligning with the same platform-level shift Google made earlier.
• PayPal is one of the nine platforms contributing sign-in data to the FIDO Passkey Index, putting a high-value financial target directly behind passkey authentication.
• Target and TikTok both appear in the same Passkey Index dataset, showing passkey adoption reaching well beyond banking and cloud infrastructure into retail and consumer social apps.
• Amazon rounds out the group, meaning one of the highest-traffic login flows on the internet now runs passkey authentication at scale.
• Crypto exchange Gemini moved toward mandatory passkey-based login rather than leaving it optional, reflecting how platforms handling high-value accounts are increasingly unwilling to keep password-only login available at all.

That last example points to where this is heading. Optional passkeys are the current norm. Mandatory passkeys, with passwords removed as a fallback entirely, are still rare but no longer unheard of, particularly on platforms where account takeover carries direct financial risk.

How Passkey Sync Differs Across Apple, Google, and Microsoft

Where a passkey actually lives depends heavily on which ecosystem created it, and that detail trips up more users than the core technology does. Apple stores synced passkeys in iCloud Keychain, tied to a user’s Apple ID and protected by that account’s own authentication. Google made passkeys the default sign-in option for personal Google Accounts back in October 2023, storing them in Google Password Manager, which syncs across Android and Chrome on any operating system rather than staying locked to one platform the way Apple’s implementation historically has. Microsoft came to a default-on passkey posture later, shifting Microsoft consumer accounts toward passkeys as the primary sign-in suggestion in May 2025, well behind Google’s timeline but still ahead of most enterprise software vendors.

The practical effect is that a passkey created on an iPhone does not automatically show up on a Windows laptop the way a Google-synced passkey does across Android and Chrome, and vice versa. Cross-ecosystem users, someone with an iPhone and a Windows PC, for example, often end up managing two separate pools of synced passkeys unless they deliberately choose a third-party, cross-platform password manager that supports passkey storage instead of relying on either platform’s native keychain. That fragmentation is probably the single biggest usability complaint in passkey adoption right now, and it is also the most likely explanation for why enrollment consistently outpaces actual usage in FIDO’s own data.

Migration Guide: Moving From Passwords to Passkeys

Switching an organization or a personal account from passwords to passkeys does not require ripping anything out on day one. Every major implementation runs passkeys alongside passwords for a transition period, and the data above suggests that period can safely last a while since passwords are not disappearing from the internet in 2026 regardless of how fast passkey adoption climbs.

1. Audit current authentication methods. List every application, internal tool, and customer-facing login that currently relies on passwords or SMS-based 2FA, and flag which ones already support WebAuthn.
2. Enable passkeys as an additional option, not a replacement. Add passkey enrollment to account settings and the login page without removing the password option yet.
3. Prioritize by risk, not convenience. Roll out passkeys first for admin accounts, financial systems, and anything currently protected only by SMS OTP, since those carry the highest exposure under NIST’s “restricted authenticator” guidance.
4. Pick a sync strategy. Decide whether the organization will rely on platform-synced passkeys (simpler for end users) or device-bound passkeys on hardware keys (stronger guarantees for high-security roles).
5. Build a fallback and recovery path before launch. Define what happens when a user loses their only device: a backup passkey, an admin-assisted reset, or a temporary use of legacy 2FA.
6. Train the help desk first. Support staff need to recognize passkey-related tickets and recovery flows before end users start generating them, since the failure modes are different from a forgotten password.
7. Set a deprecation timeline for SMS OTP specifically. Given NIST’s restricted-authenticator classification, treat SMS-based codes as the first legacy method to phase out, ahead of app-based TOTP or passwords themselves.
8. Measure enrollment versus usage, not just enrollment. The Passkey Index data shows a real gap between accounts that have a passkey enrolled and sign-ins that actually use it, so track both numbers to know whether the rollout is working.

Organizations further along in this process, including several in FIDO’s enterprise survey, report that the biggest blocker is rarely technical. It is getting users to complete enrollment in the first place, which is why pairing the rollout with a visible incentive, a security prompt at next login, or a default-on setting tends to outperform a purely opt-in announcement.

Timeline expectations matter too. Consumer platforms in the FIDO Passkey Index took roughly two years to move from initial passkey support to the 26%-of-sign-ins figure cited earlier in this piece, and those are companies with dedicated identity engineering teams and enormous user bases pushing adoption. A mid-sized company with a smaller IT staff should plan for a similarly multi-year curve rather than a single-quarter rollout, and should treat the eight steps above as a repeating cycle across departments rather than a one-time project that finishes and gets checked off.

Use Cases: Which Method Fits Which Scenario

No single method wins every scenario in the passkeys vs passwords vs 2FA comparison. Here is how the recommendation changes based on what is actually being protected.

• Consumer apps with high-value accounts (banking, crypto, e-commerce with stored payment methods): Passkeys first, with passwords kept only as an emergency fallback behind additional verification.
• Enterprise workforce identity for standard employees: Passkeys through a managed identity platform, backed by hardware keys for anyone who cannot use a company-issued phone or laptop with biometric support.
• Admin, root, and privileged accounts: Device-bound passkeys on physical security keys rather than synced passkeys, since a stolen cloud account should not be able to pull down credentials for the most sensitive systems.
• Legacy internal tools that cannot be rebuilt soon: Password plus an authenticator-app TOTP code, avoiding SMS OTP given its restricted-authenticator status under current NIST guidance.
• Shared or kiosk devices (retail terminals, hospital workstations, shared lab computers): Traditional password and PIN combinations, or badge-based authentication, since passkeys are designed around a personal device and do not fit a device shared by dozens of people per shift.
• Air-gapped or offline environments: Hardware security keys or local password authentication, since cloud-synced passkeys assume some connectivity to the platform’s backup service during setup.
• Low-risk accounts on sites without passkey support yet: A password manager generating unique, high-entropy passwords per site remains a reasonable stopgap until passkey support arrives.

Notice the pattern across these seven scenarios: the deciding factor is rarely “which method is more secure in the abstract” and almost always “what device does the person actually have in front of them at the moment they need to log in.” That is a more useful question than picking a single winner, because it is the question that determines whether a rollout actually gets used or just gets enrolled and ignored, the exact gap FIDO’s own sign-in data keeps surfacing.

Pros and Cons of Each Method

Passkeys

Pros: phishing-resistant by design, fastest average sign-in time at 8.5 seconds, highest success rate at 93%, no shared secret for a breach to expose, free on existing devices, syncs across a user’s devices automatically.

Cons: not every website or app supports them yet, cross-platform sync between different ecosystems (say, Apple to Windows) can be clumsy, account recovery when a user loses every enrolled device is still a harder problem than a password reset email, shared or kiosk devices are not a good fit, and the security of synced passkeys is only as strong as the cloud account protecting them.

Passwords Alone

Pros: supported literally everywhere, no hardware or biometric requirement, familiar to every user, zero cost.

Cons: fully phishable, reused across sites by most users despite two decades of advice not to, the single biggest target in credential-stuffing attacks, the slowest and least secure option in every benchmark cited in this article, and entirely dependent on the server storing them correctly, which is exactly the failure mode behind most credential-based breach headlines.

Passwords Plus 2FA

Pros: far better than a password alone, widely supported, familiar UX pattern for most users, authenticator-app TOTP codes are inexpensive and reasonably secure.

Cons: SMS OTP specifically is now a NIST “restricted authenticator” due to SIM-swap and interception risk, adds a second step that slows login to roughly 31 seconds on average, still depends on a phishable password as the first factor, generates more help desk tickets than passkeys according to FIDO’s data, and push-notification fatigue (users approving prompts out of habit) has become its own well-documented attack pattern against corporate accounts.

What Security Experts Are Saying

“Compared to passwords, passkeys are more resistant to credential stuffing and other remote attacks and generally offer consumers and corporations greater security.”

Twilio, cloud communications company — twilio.com

“FIDO2 credentials including passkeys are more secure than traditional multifactor authentication against all common attacks, and at all stages of the credential lifecycle.”

UK National Cyber Security Centre — ncsc.gov.uk

“Passkeys fulfill the security goals of 2FA without requiring two separate steps.”

Corbado, passkey security publisher — corbado.com

Taken together, these threenational government security agency, and a specialist authentication publisher, and all three land on the same conclusion from different angles: passkeys are not just a convenience upgrade, they close security gaps that 2FA leaves open

The Verdict: Which Should You Actually Use in 2026

For any account that supports it, passkeys are the correct default in 2026. The data backs this up from every angle covered in this comparison: a 93% sign-in success rate against 63% for older methods, sign-ins that average 8.5 seconds instead of 31.2, 81% fewer help desk incidents, and a phishing-resistance guarantee that neither passwords nor SMS-based 2FA can match. Five billion passkeys are already active worldwide, and the organizations that have deployed them report double-digit drops in both support costs and phishing incidents.

That does not make passwords or 2FA obsolete this year. Passwords remain necessary wherever passkey support has not shipped yet, and traditional 2FA, specifically authenticator-app codes rather than SMS, is still the right call for shared devices, legacy systems, and any account where a passkey simply is not an option. The realistic target for most organizations in 2026 is not “passwordless everywhere” but “passkeys as the default, 2FA as the fallback, and SMS one-time codes phased out first,” which lines up with where NIST’s own guidance has already moved.

The gap worth watching is the one inside FIDO’s own numbers: 36% of accounts have a passkey enrolled, but only 26% of sign-ins actually use one. Closing that gap, not winning the security argument, is the real work left in the passkeys vs passwords vs 2FA transition.

For engineering teams deciding where to spend the next quarter’s security budget, the highest-leverage move is rarely a full passwordless rebuild. It is turning on passkey support wherever the identity provider already supports WebAuthn, defaulting new accounts to passkey enrollment instead of a typed password, and retiring SMS OTP specifically wherever an authenticator app or passkey can take its place. Each of those is a smaller project than a full authentication overhaul, and each one moves the needle on the exact metrics FIDO, NIST, and the NCSC all point to independently.

Frequently Asked Questions

Are passkeys the same as two-factor authentication?

Not exactly. Traditional 2FA layers a second check on top of a password. A passkey replaces the password entirely with a single cryptographic step that already combines something the user has (the device) with something the user is or knows (a biometric or PIN), achieving the same two-factor security goal without a separate second step.

Can a passkey be phished or stolen like a password?

No, not in the way a password can. A passkey’s private key never leaves the device, and the cryptographic exchange is bound to the exact domain that created it, so a fake login page cannot capture a reusable credential the way it can with a typed password or a forwarded SMS code.

What happens if I lose the device my passkeys are stored on?

Synced passkeys backed up through iCloud Keychain, Google Password Manager, or a similar service can be restored on a new device tied to the same account. Device-bound passkeys on a physical security key have no cloud backup, which is why security teams recommend enrolling at least two hardware keys, or a hardware key plus a synced passkey, for any high-value account.

Is SMS-based two-factor authentication still safe to use?

It is better than a password alone, but it is the weakest widely used second factor. NIST’s current Digital Identity Guidelines classify SMS and phone-network-based one-time passwords as “restricted authenticators,” largely because of SIM-swap attacks and the ease of intercepting text messages compared to app-based codes or passkeys.

Do passkeys cost money to set up?

Not on devices that already support them. Windows Hello, Apple Face ID and Touch ID, and Android biometric unlock all support passkeys at no additional cost. Organizations that want dedicated hardware security keys will pay per device, with Yubico’s lineup currently running from $29 for a basic Security Key up to $98 for the biometric YubiKey Bio Series.

Will passwords disappear completely?

Not in the near term. Even with 5 billion passkeys active worldwide, they currently account for only about 26% of total sign-ins across the platforms FIDO tracks. Passwords will keep working as a fallback on most services for years, even as passkeys become the default recommended method.

Which is better for a small business with limited IT staff: passkeys or a password manager plus 2FA?

Passkeys generally require less ongoing management once set up, since there is no shared secret to rotate and no password-reset workflow to staff. A small business with mostly cloud-based tools (email, CRM, accounting software) that already support WebAuthn can usually move to passkeys with less overhead than maintaining a password manager and enforcing 2FA policy across every employee.

What is the difference between a passkey and a hardware security key?

A hardware security key is one way to store a passkey. The term “passkey” describes the FIDO2/WebAuthn credential itself, while a physical key like a YubiKey is one place that credential can live, alongside a phone’s secure enclave or a cloud keychain. All hardware security keys can hold passkeys, but most consumer passkeys today are synced credentials stored on a phone or laptop instead of dedicated hardware.
