@merill So... you're saying after February 27, 2023, I'll need to use MFA for Microsoft 365, and that MFA is the Microsoft Authenticator app? I can't opt-out, and I can't use a different MFA app?

@YawnTor @merill You can use other Authenticator apps. This change is just for the Microsoft Authenticator app which previously showed an Approve Yes/No option.
