Passkeys

Passkeys are a passwordless authentication method that replaces traditional passwords with cryptographic key pairs, enhancing security and user convenience. A private key is securely stored on the user’s device, while a public key is registered with the service. During login, the device verifies the user’s identity without transmitting the private key, making passkeys highly resistant to phishing and credential theft. Keycloak supports passkeys through WebAuthn, allowing users to authenticate using built-in biometric sensors, security keys, or mobile devices. Passkeys can be synchronized across devices or tied to a single device, offering flexibility in authentication. By integrating passkeys, Keycloak enables organizations to implement a more secure and user-friendly authentication experience while reducing reliance on traditional passwords.
