Is Face ID a Passkey?#

No, Face ID and passkeys are different things. However, Face ID can be used within a passkey ceremony. In general, a passkey is a secure and convenient way to log into apps or websites, utilizing biometric authentication methods like Face ID or Touch ID. When a user opts to use Face ID as local authentication method in passkey ceremonies, the device securely stores a cryptographic key pair. This key pair is unique to each account and only accessible by the device. During authentication, Face ID verifies the user’s identity by matching their facial features, which triggers the passkey to log in without needing a traditional password.

Face ID can be used as local authentcation within a passkey ceremony.
Passkeys use biometric data like facial recognition to authenticate users.
Face ID enhances security by eliminating the need for passwords.
Passkeys ensure that sensitive authentication biometric data never leaves the device.

How Face ID Works Within Passkey Ceremonies#

Face ID, a facial recognition system developed by Apple, is designed to provide secure authentication for various digital services. When used as a passkey:

Cryptographic Key Pair: Upon registering for a service, the device creates a cryptographic key pair. The public key is shared with the service provider, while the private key remains securely stored on the device.
Biometric Authentication: When you attempt to log in, Face ID verifies your identity by scanning your face. If the match is successful, the device uses the stored private key to sign in securely, without transmitting the actual biometric data or the private key to the server.
Enhanced Security: Because the private key never leaves the device, the risk of password theft or phishing is significantly reduced. This method provides a higher level of security compared to traditional password-based authentication.

Benefits of Using Face ID Within Passkey Ceremonies#

User Experience: Face ID provides a seamless and user-friendly login experience. Users no longer need to remember or manage complex passwords, reducing the friction during the authentication process.
Security: The combination of local biometric authentication and passkeys makes unauthorized access extremely difficult. Since the private key is stored on the device and never transmitted, it minimizes the risk of interception or hacking.
Compliance: Many organizations are moving towards passwordless authentication solutions to comply with stricter data protection regulations. Face ID as local authentication in passkey ceremonies aligns with these requirements by offering a secure, passwordless login method.
