Solved: Internet Explorer prompts credentials (Single Sign-on doesn’t work)

You have probably come across this prompt windows saying “Enter your credentials” at least once while using your work computer.

Enterprise companies set up SSO (Single Sign-on) in their internal networks. Thanks to SSO, Internet Explorer is not supposed to ask you credentials. What if it does?


Follow the steps below to fix this single sign-on issue:

  1. Close all Office documents including Skype
  2. Open an Office document. Go to “File > Account” and sign out
  3. Go to “Start > Control Panel > Credential Manager
  4. Click “Remove from Vault” under each section
  5. Open “Command Prompt“. Type gpupdate /force and enter
  6. Restart the computer
  7. Log back in. Open an Office document and sign in
