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?
I work for an MSP servicing 5k users all of whom I force to use M$ Auth app. Because it is the best Authenticator on the market, their company is paying for it, and because I look at the sign in logs for 3-4 different organizations every day to see literal hundreds of foreign sign-in attempts that fail due to M$ MFA. Yeah fuck monopolistic megacorps but understand when they provide an actual good product that is safe to use and actively protects you as an individual better than anything else out there.
All that said, the most likely reason is that they don’t want to make a document explaining how to set up MFA for each of the dozen+ apps out there and they certainly don’t want to talk to users who don’t know what they are doing with which ever app their kid set up for them
I’m sure you know what you’re doing better than 80% of the other employees in your office in this regard but I can tell you from experience, when one person gets their way, everyone wants theirs too.
You left out two things:
It doesn’t change anything for the company with exception to billable IT time used when the authenticator confuses users which is already high with only one authenticator.
It doesn’t report location, Entra login reports location regardless of authentication method used.
