Re: [webauthn] PublicKeyCredentialUserEntity difference between name, displayName and id not clear

Oh right, I think I can answer that myself. It's to support first factor login while making it harder for an attacker with a stolen authenticator to identify the authenticator's user, right? And that's also why you shouldn't put something identifying like an email address in `user.id`.

But wait, aren't you saying that the UI for selecting a first factor credential will display the `name` and/or `displayName` to the user? Then what would prevent the attacker from identifying the user by simply trying a bunch of first factor authentication challenges?
