A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
I think when the phone’s gone and the auth app’s wiped, the acct falls into a lock only the recovery page can break…
I’d run the reset at https://aka.ms/recoveraccount in a clean inPriv and let it rebuild the MFA from zero and it’s the only path that’s pulled folks back for me.
