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 is using windows hello on compatible machines and through persistent tokens on Mac and Windows machines not compatible with hello. You have to create that token with a known factor such as a mobile device but outside of that, users almost never have to sign in with persistent tokens.
