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?
Thanks people, some good replies here. I could demand a work phone, but that’s impractical, dragging around two phones etc. I’d like all my 2FA in Aegis and not have to think and pick the right app first, let alone pick and unlock the right phone. The Shelter option is very nice, didn’t know about that. If my company won’t budge I’m doing that. When push comes to shove I could even use outlook that way on my phone.
It’s worth adding I greatly prefer MS Auth style authentication, since I don’t have to find the right entry to read the Auth code and then write it on the other computer. Instead MS pops a notification and you either type or select the right number, verify with fingerprint and done. Much more convenient.
It often tells you what you login into and where you are attempt to log in from, so it’s a few extra layers of security for those that have that awareness to check those details.
