So my company decided to migrate office suite and email etc to Microsoft365. Whatever. But for 2FA login they decided to disable the option to choose "any authenticator" and force Microsoft Authenticator on the (private) phones of both employees and volunteers. Is there any valid reason why they would do this, like it's demonstrably safer? Or is this a battle I can pick to shield myself a little from MS?
...it won't let me edit my other comment but I wanted to add that YES using MFA is demonstratively far more safe than any password you can set.
With a multi factor enabled you could literally give your password out and people could not access your account without being able to complete that second layer of security.
