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?
Would you even need a monthly plan for this kind of thing? It just needs to be able to install the app and run it. If it needs internet you can connect to WiFi. You can get a sim free android for about £50 outright now.
