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?
You cannot be forced to give your employer access to your property, so just say that you cannot install it on your phone. Make sure you say that it isn’t possible. You don’t have to make it sound voluntary. You can just say “I cannot install this on my phone”. Even if the reason is because you refuse to install it, it doesn’t matter, that’s your call to make with your own property.
Your employer will either need to find another solution that you can use, or they will need to issue you a company phone so that you can use the mobile software they require you to use.
I work in tech, and have had multiple employees claim they only have “dumb” phones for what I’m pretty sure is this exact reason. And I never blame them, just put the heat on IT to find a solution.
