Passkeys generally provide stronger protection for sign-ins when a service supports them: FIDO2 ties the credential to the legitimate website or app, making it resistant to common phishing and replay attacks. A password manager still matters because many accounts require passwords; it can generate a different strong password for each one. For most people, the practical choice is not one or the other: use passkeys where available, and keep a password manager for passwords and account recovery.
Are passkeys safer than a password manager?
They protect accounts in different ways, so the better choice depends on what an account supports. A passkey is a phishing-resistant sign-in credential. A password manager helps you use strong, unique passwords on sites that have not adopted passkeys.
FIDO2 credentials, including passkeys, are designed so a fake website cannot simply collect a reusable password-equivalent secret. The credential is bound to the legitimate site’s origin. The UK National Cyber Security Centre (NCSC) assesses FIDO2 credentials as as secure or more secure than traditional multi-factor authentication against common attacks. The US Cybersecurity and Infrastructure Security Agency (CISA) likewise describes FIDO/WebAuthn as the only widely available phishing-resistant authentication and recommends migrating to it where possible.

But it can generate and store a distinct, long password for each account, reducing the damage from password reuse and credential stuffing—attacks that try leaked login details on other services. NIST says password managers improve security by generating unique, long, complex passwords and storing them in encrypted local or cloud vaults.

At a glance
| Security question | Passkeys | Password manager |
|---|---|---|
| Phishing resistance | FIDO2 credentials are bound to the legitimate site origin and resist common phishing and replay attacks. | Stores passwords but does not make password sign-in phishing-resistant. |
| Reuse and credential stuffing | Credentials are unique per account. | Can generate and store a different password for each account. |
| What must be protected? | The device or passkey sync account, plus recovery options. | The encrypted vault, master passphrase, MFA, and recovery channel. |
| Device loss | Synced passkeys depend on the security and recovery of the sync service; device-bound passkeys need a backup or secure recovery. | Access depends on the vault and its recovery process; the master credential is high-value. |
| Where it works | Only on services that support passkeys or FIDO2 credentials. | Useful for accounts that still require passwords. |
| Device malware | A compromised device can undermine the sign-in process. | A compromised device can undermine the vault or its use. |
The comparison is not a claim that every implementation is identical. The type of passkey, how it is backed up, the service’s recovery design, and the security of your devices all affect the practical risk.
How does each method protect an account?
A passkey replaces the password-based secret a person would otherwise enter at a site. A password manager keeps password sign-ins usable while helping you avoid weak or repeated passwords. Understanding where each method places its security burden makes the choice clearer.
How a passkey works
Passkeys use FIDO2/WebAuthn. In a passkey sign-in, the service and the device or credential manager use a cryptographic credential associated with that account. The site-origin binding is important: a lookalike phishing site cannot use the credential as if it were the real service, and there is no reusable password for the attacker to capture and replay.
On a consumer device, you commonly approve a passkey sign-in with an existing biometric such as Face ID or a fingerprint, or with the device PIN. That gesture verifies you to the device; it does not mean your face or fingerprint is sent to the website as the account password. The NCSC says that when user verification is used, passkeys and other FIDO2 credentials are themselves multi-factor authentication.

Passkeys can be synced across devices through a credential manager, or kept on a single device. Sync makes moving between devices easier, but it means the protection and recovery of the sync account matter. A device-bound passkey avoids relying on that sync fabric, but losing the device creates a backup and recovery problem unless you have registered another credential.
How a password manager works
A password manager stores account passwords in an encrypted vault and can generate a unique password for each service. You unlock the vault with a master credential, and some managers also use multi-factor authentication. This centralizes access and reduces the temptation to reuse an easy-to-remember password, but it also concentrates risk: a stolen master secret or compromised recovery route can put many stored credentials in scope.

That last recommendation reflects a trade-off: recovery that is convenient for a locked-out user can create another route an attacker may try to exploit. A stolen master secret can mean replacing every password in the vault, not just the manager login.
Which attacks does each method resist?
Passkeys have a clear advantage against fake-site phishing because FIDO2 binds authentication to the legitimate origin. A password manager’s main contribution is to make passwords unique and hard to guess, which limits reuse and credential-stuffing exposure; it does not itself stop a person from entering a password on a convincing fake site.
Phishing and replay
With a conventional password, a user can be tricked into typing a reusable secret into a lookalike page. An attacker can then try that secret at the real service or reuse it elsewhere if the person used it on multiple accounts. FIDO2’s origin binding prevents the fake page from completing authentication as the legitimate site, and passkeys are designed to resist replay.

CISA calls FIDO/WebAuthn the only widely available phishing-resistant authentication. This is why a passkey is especially valuable for accounts that are frequently targeted or that protect access to other accounts. A password manager remains a strong improvement over memorized or reused passwords, but it addresses a different part of the problem.
Password reuse and credential stuffing
Password reuse creates a chain reaction: a password exposed in one breach may unlock another account. A manager can generate a unique password for each service, so a leaked password does not automatically become a credential for the rest of your accounts. Passkeys also provide per-account uniqueness, without requiring you to remember a separate password.
Malware and device compromise
Neither method makes an infected or compromised device safe. Malware or an attacker with control of the device can undermine the environment where you approve a passkey sign-in or unlock and use a password vault. Keep devices and browsers updated, use reputable software, and be selective about browser extensions; these remain part of the security boundary for both approaches.
What happens if you lose a phone or computer with passkeys?
The answer depends on whether the passkeys are synced or device-bound. A synced passkey can be available through its credential manager on another device, but the sync account and its recovery process must be secure. A device-bound passkey may not be available after that device is lost, so you need another registered credential or a secure recovery route.
If your passkeys are synced
Confirm that you can sign in to the credential manager from a replacement or additional device and that its recovery options are protected. The sync fabric—the account and service that make the credentials available across devices—is part of the security boundary. The NCSC recommends protecting it with phishing-resistant authentication and maintaining secure recovery.

If your passkeys are device-bound
Register more than one passkey where the service allows it, or keep a FIDO2/WebAuthn security key as a backup for supported accounts. A security key can act as a physical backup or as a device-bound authenticator. Do not assume every service supports the same backup methods; check the account’s sign-in and recovery options before relying on a single device.
Before removing an old sign-in method
- Register the passkey on the account and confirm it can sign you in.
- Add a second passkey or supported security-key backup where practical.
- Review the service’s account-recovery options and make sure you can still use them if the primary device is unavailable.
- Only then consider removing an old credential, if the service permits it and you no longer need it.
This order matters because a successful passkey sign-in on your current phone does not, by itself, prove you can recover the account after losing that phone.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Should you use a password manager if you have passkeys?
Yes, for the accounts that still require passwords and for managing unique credentials during a gradual transition. Passkeys are not available on every service, so a password manager can fill the gap without making every password the same or easy to guess.
For password-based accounts, use the manager to generate a different random password for each service. Protect the manager with a long master passphrase and MFA, and secure its recovery channel. If you can choose, prefer a manager that does not offer master-password recovery, as NIST advises; weigh that choice against the possibility of losing access if you forget the passphrase.

How should you choose and set up the right combination?
Use the service’s passkey option when it is available and you can maintain a safe backup or recovery path. Keep passwords in a manager for the remaining accounts, and make sure the manager’s master credential and MFA are stronger than the passwords it protects.
- Check whether the service supports passkeys. Use its account security or sign-in settings; availability depends on the service.
- Register a passkey and test it. Confirm that the new sign-in works before removing any existing credential.
- Set up a backup. Add another passkey or a FIDO2 security key if supported, and verify the recovery process.
- Move remaining passwords into a manager. Generate a unique password for every account instead of reusing one.
- Secure the manager. Choose a long master passphrase, enable MFA, and understand how account recovery works.
- Maintain the devices involved. Keep the phone, computer, and browser updated, and use care with extensions and other software that can access your sessions or vault.
For the highest-value accounts, prioritize phishing-resistant sign-in and a recovery plan that does not depend on one device. The NCSC specifically recommends favoring passkeys where services support them, protecting the sync fabric with phishing-resistant authentication, and maintaining secure recovery.
How common are passkeys, and do users find them useful?
Passkeys are gaining adoption, but availability is not universal. In a FIDO Alliance survey in 2024, 53% of respondents said they had enabled passkeys on at least one account. In the same survey, 61% considered passkeys more secure than passwords, and 58% considered them more convenient. These are survey responses, not a measure of how many services support passkeys or a guarantee that every user’s setup is secure.

Frequently Asked Questions
Are passkeys the same as Face ID or a fingerprint?
No. A biometric can be the local method you use to unlock or approve a passkey, but the passkey is the FIDO2 credential used for the account sign-in. A device PIN can also be used for verification, so a biometric is not required in every setup.
Can a FIDO2 security key be used instead of a passkey?
A security key is a physical FIDO2/WebAuthn authenticator, and it can serve as a backup or device-bound sign-in method for accounts that support it. It is not a universal substitute: check whether the particular service accepts security keys and register it before you need it.
Does enabling a passkey mean my account has stopped using its password?
Not necessarily. Enabling a passkey adds a supported sign-in option; whether the password remains active depends on the service’s controls. Review that account’s sign-in settings rather than assuming the old credential was disabled.
