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?
That’s the solution I picked at work. Refused to install that Microsoft software on my personal phone, but instead provided a phone number.
If you have a VoIP provider you could even try to the VoIP number for MFA instead of providing your real mobile number.
If IT make a comment about you not having the app, ask if they intend to provide a company device for that.
