Removing cached login credentials in Windows XP?

Windows XP saves the username and password you use for 802.1X authentication so you don’t have to enter it every time you connect to the network. This is not a safe thing to do. To clear your credentials on Windows XP edit the registry as follows,

WARNING: Making arbitrary changes to the registry could break your operating system

  • From the Start menu open the Run... window
  • Start the program regedit
  • Carefully navigated to HKEY_CURRENT_USER » Software » Microsoft » Eapol » UserEapInfo
  • Delete any stored values in this branch of the registry tree

The Network Setup Program has an feature do do this for you.

Window 7 and Vista both have a checkbox in the network properties window that prevents your credentials from being stored.
