Keycloak has new client profiles `fapi-2-security-profile` and `fapi-2-message-signing`, which ensure Keycloak enforces compliance with
the latest FAPI 2 draft specifications when communicating with your clients. Thanks to https://github.com/tnorimat[Takashi Norimatsu] for the contribution.
Keycloak has preview support for https://fidoalliance.org/passkeys/[Passkeys].
Passkey registration and authentication are realized by the features of WebAuthn.
Therefore, users of Keycloak can do passkey registration and authentication by existing WebAuthn registraton and authentication.
Both synced passkeys and device-bound passkeys can be used for both Same-Device and Cross-Device Authentication.
However, passkeys operations success depends on the user's environment. Make sure which operations can succeed in https://passkeys.dev/device-support/[the environment].
