How fantastic it is, so you MS invented 1-factor auth, removing password from 2FA! LOL Obviously even 2FA with weak password is better than 1FA, especially when proper hash and password policy (forbid known bad passwords etc.) are combined. But it seems they think a mobile with biometric auth is better than password only, that itself is somewhat understandable.
