alt Hacker News> I suspect the next thing you're going to say is along the lines of "then just switch jobs", though.
I mean even that might not work out. We just switched to MS Teams last year and Microsoft uses a push-based app, not TOTP or other offline keys like we'd used before. And Teams just seems to be getting more popular...
Microsoft can actually use TOTP, Push, or offline keys.
Which of them are available depends on what your company has configured.
If the push version is configured, it's possible it has also installed an MDM profile on your device. Avoid that, or your phone will get wiped when you leave the company in the future.
