Re: [webauthn] The risk of attacker may can identify whether if the account support FIDO or not (#1475)

It might depend on how RP handles such NRK authentication request. 

- Ideally, RP might simply return randomly generated credential id which makes the attacker harder to distinguish
- RP might introduce reCAPTCHA or something to block automated try (brute force)
- To slow down the attacker's attempts, RP might introduce rate limiting (exponentially increasing timeout)
- RP might leverage NRK just for step-up authentication
