Biometrics are reshaping authentication mostly by making it easier to use a cryptographic credential, such as a passkey. In many passkey flows, your device checks your face or fingerprint locally and then uses a private key to prove your sign-in to the service. The biometric is not necessarily sent to the website. That can reduce password and phishing friction, but it does not make a biometric a secret, guarantee a match is genuine, or remove the need for accessible fallback and account recovery.
How do biometrics work with passkeys?
A passkey is based on a cryptographic key pair: a private key held by an authenticator and a public key registered with an online service. When you sign in, the service sends a challenge; the authenticator uses its private key to answer it. The biometric check on a device can authorize use of that key. The service verifies the cryptographic response rather than receiving your face or fingerprint as a password.
FIDO2 combines WebAuthn and CTAP and supports both authenticators built into devices and external authenticators such as security keys. FIDO describes passkeys as unique and bound to the online service domain, and says biometric information, if used, never leaves the user’s device. That describes the FIDO architecture; it is not proof that every product handles all biometric data, diagnostics, or related information identically. Check the privacy and security details for the particular device, platform, and service.
A fingerprint or face match is therefore often a local user-verification step, not the credential the website checks. A device may use a PIN instead, depending on its configuration and the service’s supported sign-in methods.

Does my face or fingerprint get sent to websites?
In the FIDO passkey model, the biometric stays on the device and the service receives cryptographic proof. That is different from a system that sends a biometric sample to a central service for comparison. Do not assume that every biometric login follows the FIDO model: handling depends on the implementation, and users should consult the provider’s documentation for specifics.
Central matching creates additional privacy and security responsibilities because biometric data must travel to, or be stored by, a comparison service. NIST SP 800-63B-4 calls for authenticated sensors and endpoints and protected communication channels for central comparison, as well as appropriate protection of biometric data as sensitive personal information. Central storage also raises the stakes of access control and a data breach: a face or fingerprint is difficult to replace if exposed.

USB 3.0 docking stations are prone to power supply/interference and unstable recognition.
Are biometric logins secure?
They can be useful as one part of a well-designed authentication flow, but a biometric is not a secret and should not be treated as a password equivalent. NIST notes that faces, latent fingerprints, and iris patterns can sometimes be obtained without a person’s consent. Matching is also probabilistic: sensor noise, the match threshold, and the quality of a sample affect whether a legitimate user is accepted or rejected.
NIST SP 800-63B-4, published August 1, 2025, is the current NIST digital identity guidance used here; it supersedes SP 800-63B. It says biometrics “SHALL only be used as part of multi-factor authentication with a physical authenticator (i.e., ‘something you have’).” It also says a biometric must be presented and compared for each authentication operation, an alternative non-biometric option must always be available, and biometric data must be secured as sensitive personal information. This is U.S. federal guidance, not a universal law or a binding rule for every private service.

Accuracy is not the same as spoof resistance
NIST’s stated biometric system requirements set a false match rate (FMR) of one in 10,000 or better across demographic groups, and say the false non-match rate (FNMR) should be below 5%. FMR concerns an incorrect match between different people; FNMR concerns failing to match the person enrolled. NIST requires presentation attack detection (PAD) for facial recognition and recommends it for iris and fingerprint systems. PAD addresses attempts to fool a sensor, a different issue from ordinary matching accuracy.
These are requirements and recommendations in NIST guidance, not evidence that every consumer device has been independently assessed against them. A device’s convenient face or fingerprint unlock should not be presented as proof that its sensor meets a particular assurance level.

A match does not always prove intent
Recognition and deliberate approval are separate questions. NIST points out that a front-facing camera could capture a face during ordinary device use. An explicit action, such as tapping a button to approve a sign-in, may be needed to show that the user intends to authenticate. For sensitive actions, consider whether the flow requires an intentional confirmation rather than relying only on a sensor detecting a face.

| Approach | What it offers | Trade-offs to assess |
|---|---|---|
| Device-bound key with local biometric | A biometric can unlock use of a cryptographic key tied to an enrolled device. | Plan for a lost, damaged, or inaccessible device; verify backup, recovery, lockout handling, and a non-biometric route. |
| Syncable passkey | Can make a cryptographic credential available across devices and simplify recovery. | NIST describes syncable authenticators as inherently exportable: their private keys can be cloned and stored separately to support use on multiple devices. Evaluate cloud-account security, recovery controls, sharing behavior, and whether synchronization is suitable for the use case. |
| External FIDO2 security key | A separate physical authenticator can work with compatible FIDO2-enabled browsers and platforms. Depending on the key and platform, connection can use USB, NFC, or Bluetooth LE. | Check compatibility and plan for loss, backup keys, or another recovery route. The key is an authenticator, not a biometric sensor, and does not itself establish a person’s identity through a face or fingerprint. |
| Central biometric matching | Allows a service to compare biometric data centrally rather than relying only on a device-local match. | Requires stronger controls for authenticated sensors and endpoints, protected transmission, access, and sensitive stored data; it adds privacy and breach concerns. |
What happens when a device is lost or a biometric check fails?
Before relying on a biometric sign-in, identify how you will regain access if the sensor cannot verify you, the device is lost, or the account’s recovery method is unavailable. NIST’s requirement for an alternative non-biometric option matters in practice: people may be unable or unwilling to use a particular biometric, and sensors sometimes reject legitimate users.
- Confirm which non-biometric sign-in option is available, such as a device PIN or another supported authenticator.
- For a device-bound key, understand how a replacement device will be enrolled and whether another authenticator can be used meanwhile.
- For a syncable passkey, secure the account or platform that manages synchronization and review how its recovery process works.
- If using a separate security key, consider how to recover access if that key is lost and whether the service supports a backup key.
- Review recovery methods as part of the security design: a robust biometric or passkey flow can still be undermined by weak account recovery.
What does passkey availability say about adoption?
NIST’s 2024 explainer relayed a FIDO Alliance estimate that more than 8 billion user accounts had the option to use passkeys. That figure describes account eligibility, not the number of people who adopted passkeys or actively use them; NIST explicitly cautioned that it does not show those users opted in.
