[id="passkeys_{context}"] === Passkeys {project_name} provides preview support for https://fidoalliance.org/passkeys/[Passkeys]. {project_name} works as a Passkeys Relying Party (RP). Passkey registration and authentication are realized by the features of xref:webauthn_{context}[WebAuthn]. Therefore, users of {project_name} can do Passkey registration and authentication by existing xref:webauthn_{context}[WebAuthn registration and authentication]. [NOTE] ==== Both synced Passkeys and device-bound Passkeys can be used for both Same-Device and Cross-Device Authentication (CDA). However, Passkeys operations success depends on the user's environment. Make sure which operations can succeed in https://passkeys.dev/device-support/[the environment]. ====
