Clear stored TFS credentials in Visual Studio 2017

Please try below items to narrow down the issue:

• Remove the TFS related credentials from Credential Manager

• In Credential Manager add the new updated Generic Credentials for the TFS account. Generally, this would overwrite the cached credentials.

• Close all Visual Studio instances, delete %LOCALAPPDATA%\.IdentityService as you did.

• Clear TFS caches %LOCALAPPDATA%\Microsoft\Team Foundation\7.0\Cache

• Clear all the browser caches especially for the stored password

• Restart Visual Studio > Team Explorer > Manage Connections to check if the Enter credential dialog popup. Just try this several times. Based on my test the dialog will popup the first time, but if you cancel it, then you have to restart VS to popup it again.

• Run Visual Studio as another user:

  cd C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE

  runas /netonly /user:<account> devenv.exe

  Enter the user possword, then Team Explorer > Manage Connections

Clear the config from the following path:

C:\users\<user>\AppData\Roaming\Microsoft\VisualStudio\15.0_????\Team Explorer\

I tried to follow the steps listed in the other answer. But on first step I decided to try just editing the password in credentials manager. It worked for me.

So if anyone else is having the same problem you might want to try that first.
