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?
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).
