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?
≥ and force Microsoft Authenticator on the (private) phones of both employees and volunteers.
Refuse to use the service until they provide you with a work appointed phone. Volunteers admitedly have a more difficult time with that but as someone else said you can indeed do text/call options.
Who cares? It's a work phone that is used only for work, they are entitled and expected to track it as much as my work laptop or any other company equipment. That's not a privacy issue unless you're using company resources for personal stuff. If I don't want them tracking me I just turn it off or leave it at home.
The point is that the phone will be tracking 24/7 regardless of your actual availability.
A faraday cage on your work desk can take care of that during off hours, especially since most batteries have become non-removable and phones don’t truly shut down anymore. Just put your work phone into the cage when your shift ends, take it back out when your next shift starts. Easy peasy!
And if they demand 24/7 access, they will need to provide 24/7 pay.
Not sure I understand what the faraday cage would accomplish. It's the companies device. You'd be skipping this presumption outlined earlier in the thread
they are entitled and expected to track it as much as my work laptop or any other company equipment.
Leaving the work phone at work is a valid answer to me. Assuming that doesn't actually come with any other downsides (working offsite and having to return to the office on unpaid time just to drop off the phone for example).
And my point was that a separate corporate device makes it trivial to manage my privacy and availability. Using my personal phone for work is a hard NO.
If I don’t want them tracking me I just turn it off
Are they entitled to it or not? If they're entitled, then why do you have a right to cut it off? I'd argue they have no right to it to track me off hours at all... regardless of the device used. u2f tokens like yubikey would be just as sufficient for 2fa with none of the tracking.
Or I brought up a point that you didn't consider, and rather than addressing it you need to resort to low level ad hominem. You contradicted yourself. Either explain the contradiction or move on. There's no point in this comment unless you're attempting to discredit me without reason which just makes you look bad.
Not much of a privacy risk if it where used for a dedicated purpose and just left off in a drawer otherwise though. My employers pushed the notion of MS authenticator, but left the options to use regular TOTP available, just had to look a bit to find them. Even if they absolutely forced corp software though, a cheap wifi-only setup device is a viable option.
Agreed. From a privacy perspective, it is a lot safer to run the app in an environment where you have admin control. E.g. disable when not in use, block access to sensitive device information, limit background and network activity as much as possible.
