[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 registraton 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]. ====
