passkeys

Authenticate Start

Begin passkey login.

If the client includes a handle hint, we return the credential IDs registered for that handle so the browser can prompt for the right one (username-first flow). If not (usernameless / discoverable credentials flow), we return only the challenge — the authenticator resolves which credential to use on-device.
