But a passkey does not make an entire account impossible to take over. Weak password or recovery options, a compromised device, or access to the account that syncs passkeys can still put the account at risk.
Why passkeys resist phishing
A passkey uses public-key cryptography. The service keeps a public key and asks the user’s authenticator to produce a cryptographic response using the corresponding private key. The authenticator releases that response only after local authorization, such as a device PIN or biometric check; the service does not receive a reusable password-like secret.

WebAuthn binds authentication to the identity of the site requesting it. A passkey created for the genuine site is not simply offered to a different domain, so a user does not have to spot every lookalike login page to avoid handing over that credential. NIST describes WebAuthn as an example of phishing resistance through verifier name binding in its Digital Identity Guidelines, SP 800-63B. This is a stronger defense against fake-site credential collection than a code that a user can be tricked into entering on the wrong page.
What a stolen public key or passkey means
A service’s public-key database is not a password list
If a service’s database of public keys is exposed, those keys do not by themselves let an attacker derive the matching private keys or sign in as users. That differs from a password database containing reusable secrets, although a breach can still expose other account data or create risks unrelated to passkey authentication.

“Stolen passkey” can mean several different things
A passkey is not normally a string that a user reads and types into a website. The practical risks are usually that an attacker gains control of a device or can authorize use of its authenticator, or gains access to the account or recovery process that stores and restores synced passkeys. A passkey’s phishing resistance does not protect against those forms of compromise.
How passkeys can still be bypassed
Password and other fallback sign-in
If a service still accepts a password, an attacker may target that route instead of the passkey. A strong passkey sign-in does not neutralize a weaker alternative that remains available. FIDO Alliance’s guidance recommends applying phishing-resistant protection across login, fallback, and account recovery; it says a passkey-only strategy is the approach for services seeking full prevention of phishing-based sign-in. See FIDO Alliance’s 2025 guidance on phishing-resistant authentication scenarios.

Recovery paths
Account recovery may allow password resets or rely on email, SMS, recovery codes, or support procedures. Those routes can reintroduce phishable or interceptable steps even when normal login uses a passkey. Review how the service recovers an account, and secure the email address, phone number, and provider account that its recovery process depends on.

Device and provider compromise
If malware or an attacker controls a device, or can authorize the authenticator, the basic protection against fake websites is not enough. For synced passkeys, the sync provider’s account security and recovery process also matter. NIST identifies the sync fabric and its recovery process as potential weaknesses if an attacker gains unauthorized access.

Protection differs by provider. For example, Apple says iCloud Keychain is end-to-end encrypted and describes recovery as requiring Apple Account authentication and a text message to the registered phone number. That is Apple’s design, not a guarantee about every passkey provider; see Apple’s explanation of passkey security.
Synced passkeys, device-bound passkeys, and security keys
These options make different trade-offs between availability, control, and recovery. The right choice depends on the account’s importance, the service’s support, and whether strict device boundaries are required.

| Option | Main benefit | Main trade-off | When it may fit |
|---|---|---|---|
| Synced passkey | Available across compatible devices and may be restored through its provider. | Security and availability partly depend on the sync-provider account and its recovery process. | A convenient choice for many users who secure the provider account and its recovery methods. |
| Device-bound passkey | Credential remains tied to a particular device, supporting tighter device boundaries. | Loss or replacement of the device may require another registered credential or an account-recovery route. | Consider where strict device control, elevated privileges, or regulated requirements call for it. |
| FIDO2 security key | A physical authenticator that can be stored separately and may serve as a recovery credential. | The service must support the specific key; it also adds carrying, backup, training, and lost-key recovery considerations. | An optional backup or high-assurance choice for compatible accounts; it is not required to use passkeys. |
Microsoft’s guidance for Microsoft Entra recommends device-bound passkeys when strict device-boundary control is a hard requirement and synced passkeys for other user populations. It also recommends FIDO2 security keys for highly regulated environments or elevated-privilege users, while noting associated equipment, training, help-desk, and lost-key recovery costs. These are enterprise recommendations, not universal consumer rules; see Microsoft Entra’s passkey guidance.

What to do before relying on a passkey
- Check the service’s alternatives. Find out whether password sign-in remains enabled and what the service accepts for account recovery. A passkey cannot compensate for a weak fallback route.
- Protect the account that syncs the passkey. Use strong, phishing-resistant sign-in for the provider account where available, and review its recovery options and trusted devices.
- Plan for device loss. For a synced credential, understand how the provider restores access. For a device-bound credential, register another supported credential or confirm the service’s recovery process before losing the device.
- Consider a separate security key only if it fits. Check that the service supports the specific FIDO2 key and decide how it will be stored and recovered if lost. It is an optional backup, not a prerequisite for passkeys.
- Keep devices and recovery channels under your control. Secure the device used to authorize passkeys, and protect the email and phone number that account recovery relies on.
Are passkeys safe for everyday accounts?
For ordinary phishing threats, passkeys offer a strong practical improvement over passwords and one-time codes because authentication is tied to the genuine site rather than to a secret a user can be tricked into revealing. Their real-world protection depends on the rest of the account: remaining sign-in routes, recovery, device security, and—when credentials sync—the provider’s account protections. No measured reduction rate for phishing or account takeovers is established here, so passkeys should be understood as a strong defense, not a guarantee.
