System-preferred MFA not (quite) working as expected
So I've ran into an interesting issue in my tenant today while checking some reports on the usage of various authentication methods. We enabled system-preferred MFA for all our users a few months...
if a user registered both SMS and Microsoft Authenticator push notifications as methods for MFA, system-preferred MFA prompts the user to sign in by using the more secure push notification method.
Yes, I'm aware of how it should work, it's just that it doesn't affect all our users as I described above.
