I agree, but it sounds like we’re trying to get the web browser to simplify and implement OAuth2 and OpenID Connect via WebAuthn ... If we already have OpenID Connect, the only advantage to end users under that scenario is a login-with-Apple ease-of-use improvement. Seems more likely that we’ll continue using OAuth2 and OIDC server side for this, for now... but maybe we’ll end up standardizing the ways MFA is requested and presented by providers...
