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?
Just say you don't have a smartphone....you have a flip phone...
Recently looked into this, pretty much 100% of currently-available flip phones are still smartphones under the hood, running either Android or KaiOS. And you can still install apps on these phones.
The only truly “dumb phone” appears to be the Rotary Un-Phone, or a vintage feature phone from the early 2000s that boots straight from ROM - instant-on, no visible boot process whatsoever.
