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?
Strong disagree with Microsoft Authenticator being well done - anything that is needlessly incompatible with competitors is bullshit. Either make your authenticator use the standard or fuck off.
Push Authentication in the MS Authenticator is Microsoft’s proprietary thing. And I think that’s probably what we’re talking about here.
There’s half a dozen other apps that do similar stuff, PingID, SecurID etc.
Might be interpreting your comment wrong, but it is compatible with competitors. You don’t need to use Authenticator as your 2FA for a personal Microsoft account, and you can use Authenticator in place of any other TOTP app. It’s OP’s IT department that have chosen to disable the option to use other apps.
