Hi.. I have the Windows Teams app running, and then enforced MFA on my account. Now Teams is stuck in a loop asking me to login, and I click on the button "Login now" and it just restarts and comes back up.
It shows error code: 3399614476
I had to right-click to choose Logout, and then it restarts (by itself) and allows me to log in, and then sends my temp auth code to my device.
PROBLEM ALSO HOWEVER!! is that it has no place to use my app code!

I use MFA on many of my/our tenants and Microsoft Teams works just fine.
1) tried to access it through the web?
2) tried to use the "log out" feature available when you right click the Teams logo in the system tray
3) uninstall and install the Teams app

I thought I mentioned in my post that I had to use Log out and then I could log in. But I'm explaining the user experience that is an issue.

So it seams that the Android version of MS Teams can't login at all, even using an app password as the PW.

Ya... the app PW works fine for Skype 4 Biz on Android, but not at all for Teams on Android.

If you have AD FS enabled, make sure to go over this thread: https://techcommunity.microsoft.com/t5/Microsoft-Teams/Modern-Auth-fails-in-Teams/td-p/66213

That is complicated. (Typical Microsoft).
However the issue remains with Teams on Android, which is not related to any Windows domain setting.

Same, as has all of our users. It'd be mass chaos if Teams and Android didn't work. People would be at my desk with pitchforks.

I was trying to look for this post in the huge forest of forums related to Microsoft and I just couldn't find it. I was going to update that it is working, but it wasn't until some update got applied to my Teams version.

Hi. We just turned on Multi-factor authentication for my own account and this same problem occured.
I was able to fix this by closing MS Teams, then delete every MSTeams entry in Credential Manager. Once I re-opened teams, the authentication window properly asked me to enter my code from my MS Authentication app.
Edit: (Added Credential Manager screens below)
Credential Manager stores your account credentials for the Web and other Windows services. You can open it by searching or running, Credential Manager.
Within Credential Manager, you will want to look at "Windows Credentials", and find the entries for anything relating to MSTeams. For each entry, click it to expand, and select "Remove".

For those who don't know, can you explain "delete every MSTeams entry in Credential Manager"?
