You probably want `IAuth` instead

This is the browser half on its own: it runs a ceremony and hands back what the authenticator signed, leaving the challenge and the verification to you. If you are adding passkeys to an app's accounts, Rask.Auth already does both ends — auth.AddPasskey("MacBook") and auth.SignInWithPasskey() — with the credential stored and the signature verified server-side. See Passkeys.

Reach for IWebAuthn directly when the relying party is somebody else's server, or when you are verifying the ceremony yourself.
