Question

Hi,

I have an MS 365 for Business account. I've been using MS Authenticator to log into everything, even my admin account.

I upgraded my phone and can no longer log into MS authenticator. I also did not setup ANY alternative methods to authenticate. I'm caught in a loop of not being able to login to anything because I have 2FA set to active, and no alternatives.
