Can I refuse MS Authenticator? (lemmy.ml)

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?

The ms authenticator works in 'reverse' in that you type the code on the screen into the phone. I assume this is preferable to corporate as you can't be social engineered into giving out a 2fa token. It also has a "no this wasn't me" button to allow you to (I assume) notify IT if you are getting requests that are not you.

I don't believe that the authenticator app gives them access to anything on your phone? (Happy to learn here) And I think android lets you make some kind of business partition if you feel the need to?

I mean the only real issue I see with this is that they require people to use their personal phones for this. Should not mix work and private data, and this should be in the interest of the corp, too. As in, issue work phones!

From a practical PoV - most people have their phone on them all the time. A work phone or a physical token can (and will) get forgotten, a personal phone much less.

Yeah but legally it's a bit more iffy once something gets breached and then it turns out that no, private phones are not covered by the stuff you signed for work security (because they usually cannot be, rather most written stuff explicitly forbids people from using their private phones for stuff like this, even in company who expect workers to do it).
