Stuck in a login loop after password change
I recently change my system password, with MS Teams is already up and running in the background. I open Teams to check new messages, and it locks the app with the pop up "Can you please sign in again? Sorry for any inconvenience. Login Now"
I click Login Now but all it does is restarting MS Teams and show me the same message. I am unable to re-authenticate. I've tried restarting the application, that didn't work.
I had to right click on the systray icon to logout and re-login. I should be able to re-login when the app prompted "Login Now"

Thank you for your feedback, we have fixed the issue in regards to token expiration for builds after 1.3.00.4461. If you change your password, you should no longer get stuck in a login loop.

Having the same issue, clearing the cache and credentials manager works but its not something I want to do for every user every time they change their password.

I had previously tried everything but this seemed to work for me;
- launch teams
- right click tray icon and select "sign out"
- make sure teams is closed (you might have to check task manager)
- close all office apps
- clear ALL Microsoft credentials in credential manager
- relaunch teams and you should be prompted for email and password:)

Our users have the same problem, but in our case they did not change password before. This is a particularly big problem when the issue happens during an online meeting, especially if it is a presenter or board member of enterprise.

Stunning that Microsoft hasn't resolved this issue in 3 yrs and we need to put our users through an extraordinarily kludgy workaround. They own the entire stack for this issue. They want folks to drop Slack for this? The sad part, of course, is we're doing it. We're adopting an under-supported product about which Microsoft appears not to care. Alas, not caring appears to pay off.

I ran into this issue as well.
1. Right click teams icon on system tray
2. Click sign out
3. When login screen prompts with your email, type in another user's email click sign in.
4. When it prompts you with password, click sign in with another account.
5. Type in your email and password. It should work now. -

Tired of trying. Been a member for at least 5years. Signed up with my ms team but now asks if I signed in with
Facebook. I have now with both the asks
me to sign in again! I do like to see what’s going on but to sign in 3 x is a hassle I don’t need! -

3.Click "users" tab.
4.Right click on your user name, and click "manage user accounts".
5.To the left click "manage your credentials."
6.Click "windows credentials"
7.Delete any entry under "generic credentials" that is titled starting with "msteams"
8.Reboot. Relaunch app. It should login.This worked for me.

I was finally able to log back in. I tried everything that I could find (deleting cache, restarting computer, etc, etc) but nothing worked. About a half hour ago, it started working again. I guess it was a random birthday present to me?

Using the delete the cache from keychain worked, kind of. It enabled me to log in successfully to MS Teams, however, we are using a company O365 account and now my calendar, teams, chats, and files are missing. I'm sure they are not deleted ... just inaccessible due to some other entities that may have been in the cache. I have no idea how to bring them back.

Same issue here. Attempting to sign in with a fake account worked. Then it actually asked for my password and I got to use my auth app to verify.
No recent password change at all.
It's concerning because apparently the "let's try signing out" doesn't actually sign you out, like at all. It still attempts to use some sort of cached last used creds. That's bad design.

I changed my password on Friday and I am also no longer able to log into Teams. In any format (web/client/mobile). Teams is the only Office app related; Outlook, OneNote, etc are all fine.

I just changed my password this morning and am now seeing this same issue. I can currently only log on on my phone...so frustrating! Windows PC and none of the workarounds are working for me!!

Finally found a solution for mac users.
1. Open Keychain Access
2. Select "All Items" under Category
3. Search for item "Microsoft Teams Identities Cache"
4. Delete "Microsoft Teams Identities Cache"
5. Open the Teams App, it will ask you to login and once logged in everything works as usual -

The imaginary user thing worked for me when I logged out (after right-clicking tray icon), tried to login with that, then followed up with my actual login ID. Hope that helps for more of you.

This just happened to me today. Stuck in an infinite loop. The workaround suggested by many to logout in the tray and then try to login as an imaginary user did not work. It still seems to have my old credentials cached even after that.

This is happening more often lately and what's worrying is that there is no clear reason for it; whenever someones changes passwords its russian roulette with MS Teams after.
Please fix asap.

Microsoft, I love you but ever since the end days of Messenger, your messaging apps have been terrible.

Can we make the teams app on the desk-phone authenticate like the Teams desktop app? Having the user type into the phone every time they reset their password can be hard to sell.

Same problem at a customer.
To me this seems to be a bug, because I can workaround the issue when I input some username value in the first login prompt, that doesn't make sense.Than I am redirected to a new login prompt that is familar to me, too. It looks like the normal Office 365 login dialog. There you enter the right username and on the following page the right (new) password and it is working again.
