Because the TFS Server where I work is not on the domain, it will prompt you for credentials each time you log in (unless you’ve previously used the web access and checked the “Remember Me” option). If you don’t want to use the web access portal, you can still get TFS to remember your credentials and not ask you each time you log in.
Go in to the control panel and select “User Accounts”
In the next screen click “Manage Windows Credentials”
In the next screen click “Add Windows Credential”
Then type your details into the form, and press “OK”
You’ll see your new set of credentials appear in the Credential Manager page:
Now when you open up Visual Studio it won’t prompt you for your credentials all the time.
