Fix: Microsoft Teams Error Login Hint is Duplicated

 

Imagine preparing a presentation for weeks, and Microsoft Teams fails to respond to your login request right before the meeting is going to start. Your instinct tells you to go for the ‘One size fits all’ approach and reboot your PC, but nothing works. Wouldn’t that be embarrassing and depressing?

If you are finding yourself in a similar situation, you are in the right place. Microsoft Teams can sometimes fail to respond, and this guide will walk you through the troubleshooting steps to get you back on track. 

Let’s get started. 

 

1. Clean Team Login Credentials. 

Credential Manager is a Windows program that stores information such as usernames, passwords, and application certificates. This program lets you view and remove your saved credentials for signing into apps and web pages. 

There are times when a corruption error within the ‘Credential Manager’ stops it from opening certain apps. If you face an error while logging into the Microsoft Teams app, try to clean Microsoft Teams login credentials via ‘Credential Manager’. Hopefully, it will resolve the error on your PC. 

Here is what you need to do:

  1. Close the Microsoft Teams app and type Credentials Manager in the search bar.
  2. Click on Open to launch the Credentials Manager window. 
  3. Inside the window, click on Windows Credentials
  4. Locate Office 365/Microsoft Teams and expand the option by clicking on the drop-down menu.

  1. Now, select Remove and once the credentials are removed, close the window. 
  2. Finally, relaunch Microsoft Teams and try to sign in to your account. 

You should now be able to log in without any issues. If you removed Office 365 credentials instead of Microsoft Team credentials, repeat the same process as mentioned above to sign in to your Microsoft Office account again. 

 

 

2. Perform a Clean Installation. 

A clean installation is another easy yet effective way to resolve the login error on your PC. In a clean install, the older version of the application, including all data, is eradicated, and the app is installed again. The alternative to clean installation is performing an upgrade, but an upgrade does not entirely erase previous data. 

If a bug in the application is causing the login error in your Microsoft Teams account, performing a clean install will fix the issue.

Here is how you can perform a clean installation:

  1. Type Apps and Features in the search bar and click Open to launch the window. 
  2. Locate Microsoft Teams and Teams Machine-Wide Installer. Uninstall both the programs by selecting the Uninstall option.

  1. Once the removal is complete, press Windows + R keys simultaneously to open a Run dialogue box. 
  2. Inside the dialogue box, type the locations mentioned below one by one and hit Enter. Delete all the files in these locations. 
%LocalAppData%\Microsoft\Teams
%LocalAppData%\Microsoft\TeamsMeetingsAddin
%AppData%\Microsoft\Teams
%LocalAppData%\SquirrelTemp

 

  1. Once done, restart your PC and check if you can now login into your Microsoft Teams account without any issues. 

Performing a clean install will fix most of the bugs within the application, if not all. However, if you still are unable to login and your screen still displays the Microsoft Teams error ‘login hint is duplicated’, proceed to the next method below. 

 

 

3. Use the Web-based Microsoft Teams. 

If the quick troubleshooting steps aren’t working on your device and you don’t have the time to proceed with the lengthy steps, such as reinstalling the app, try using the web-based Microsoft Teams. 

 

Microsoft Teams Desktop App

 

Web-based Microsoft Teams is similar to the desktop version, so you don’t have to worry about the quality getting compromised. Simply log on to Microsoft Teams Web Client by entering your credentials. Once you are done with the work or have attended the meeting, you can continue with the troubleshooting steps to use the Microsoft Teams desktop app. 

 

 

4. Clear Microsoft Teams Cache. 

Cached files are temporary files on your PC that help improve the overall user experience. Both web browsers and apps maintain their own cache, but unfortunately, there are times when cached files get corrupted. As a result, you encounter errors while using applications. 

This issue can be simply solved by getting rid of the relevant cached files on your PC. We also recommend clearing cache after you uninstall an app as some data fragments can be left behind. Doing so will increase your chances of solving the issue. 

Here is what you need to do: 

  1. Type Run in the search bar and hit Enter to launch the dialogue box. 
  2. Inside the dialogue box, type ‘%appdata%’ and press Enter
  3. Locate Microsoft from the list of folders appearing on your screen. 
  4. Click on Microsoft and then right-click on Teams

Clear Microsoft Teams Cache

 

  1. Delete the contents of the entire Teams folder and close the window. 
  2. Once done, try logging in to your Microsoft Teams account again and check if doing so resolved the Microsoft Teams ‘login hint is duplicated’ error. 

You should now be able to log into and use the Microsoft Teams desktop app without any issues. 

 

 

5. Try Using CleanMyPC.
