Rant on: I use it in-browser on Linux also: Microsoft's security system is horrendous. I have to log into Teams-based client meetings using incognito browser windows because Teams keeps getting into mystery login loops with regular windows. It was working for a while, but I needed to log into Intel for Altera FPGA information. Well Intel uses Microsoft Azure for identity management (I had to log into Microsoft to log into Intel). After I did this, I couldn't attend client meetings anymore. I'm pretty sure the root of the issue is that I have multiple Microsoft identities, and their security model does not handle this case well, or at least it's incomprehensible to me and I don't want to waste any more time on it. Now Microsoft also knows me via github which is screwing it up further. It tries to tie your identity to your phone number, but it will not allow multiple account on a single number. It's a nightmare. Oh yeah, Microsoft also insists on having me install a phone app for identity management, but it doesn't solve any issues (I can't log in) other than wasting my time. This is the only thing I have to use Microsoft for, and the experience sucks. F* Microsoft.
Say what you will about Google, at least I never had these issues.
The state of louisiana has a similar issue with their domain servers - if you have an errant client somewhere, anywhere, that has the wrong password (or whatever their IDS thought was 'fishy',) you get locked out of your desktop in the office. for two years my wife had to call State I.T. every morning to get logged in. Her office locked so no need to log out until quittin time.
i was never able to track down what device it was, we reformatted a couple of laptops, wiped a couple phones.

Edit: I'm not the only who constantly has this issue, see: https://techcommunity.microsoft.com/t5/microsoft-teams/teams...
