Navigating Frequent Microsoft Teams Authentication Failures

Microsoft Teams is designed as one of the best messaging programs to help you and your team. However, it may run into the occasional glitch and keep asking you to sign in.

If this has happened to you, here are a few troubleshooting tips to help you fix the issue.

1. Update Microsoft Teams

Microsoft constantly releases new app updates to add more features and fix any bugs. If you’re running an old Teams version, you should install any available updates to stop it from asking you to sign in.

Launch the Microsoft Teams app and open the three-dot menu next to your profile icon. Then, head to Settings and click About Teams. Microsoft Teams will check for any available updates and install them if available.

Alternatively, you can update Windows apps through Microsoft Store.

2. Use Microsoft Teams Online

If updating the app didn’t stop Microsoft Teams from asking you to sign in, there’s an easy alternative for you. Use Microsoft Teams online.

Go to the Microsoft Teams website , and sign in using your credentials. This way, you’re not missing anything while you figure out how to fix the desktop app. You can even join a Microsoft Teams meeting on your smartphone .

3. Clear the Microsoft Teams Cache

Microsoft Teams stores cache to load faster and improve the overall user experience. While this may sound good, if the app collected too much cache or the cache somehow got corrupted, Teams will stop working properly.

This might include Microsoft Teams crashing , taking a lot of your system resources, or repeatedly asking you to sign in. To fix it, you should delete the Microsoft Teams cache.

1. Press Win + R to bring up a Run dialog.
2. Type %appdata% and click Ok.
3. In the File Explorer window, head to Microsoft > Teams.
4. Select all folders and permanently delete them.

Restart Microsoft Teams and check if the issue is now solved. You may notice a decline in the app’s performance, but there’s no reason to worry. The app is now rebuilding its cache which shouldn’t take too long.

4. Remove the App’s Credentials

Windows Credential Manager is designed to make your life easier, as it stores your credentials for faster access. But if something’s wrong with how it managers Teams credentials, you might run into the sign-in issue. In this case, you should remove the app’s credentials.

1. Press Windows key + R to bring up a Run dialog.
2. Type control /name Microsoft.CredentialManager and press Enter.
3. In the Credential Manager window, select Windows Credentials.
4. From Generic Credentials, click the Microsoft Teams credentials.
5. Select Remove.
