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?
Not a good solution but a decent one. Create a work profile on your phone, using Shelter (Fdroid, open source), and put all your work apps on that. Your data and processes are isolated and you can turn off all your work apps with a single tap. It's like a secondary virtual phone.
If information is ever subject of a subpoena, your phone could be seized as evidence.... OS separation doesn't matter. Just like you wouldn't check corporate email or keep corp documents on your personal laptop...because your laptop could be seized for any corp legal action
I have never been involved in anything like that, so I don't know how big of a risk that actually is for most people.
And I would think as we get more and more cloud dependent any data on the phone would also be stored in company servers. So I am not sure the value a subpoenas for phones would be.
If it gets that far I would wonder if there could be a case for them of taking both personal and work phones as well just to be sure no one was talking outside of the company's standards communications.
Again I Have no idea how legally that would all go down, but I do think you being up a very good point the more speration you have between personal and work the less grounds legal action has to stand on to enter into your personal devices.
