You can add, remove, or edit credentials as well as backup and restore your saved credentials to or from a file. This is a more straightforward way to remove problematic cached credentials without having to resort to deleting your browsing history, cookies, or the like.
You can also use the “Manage Network Passwords” control panel applet. Click Start, type “Manage Network Passwords”, then press Enter with that item selected or Click on Start –> Control Panel, click on the “User Accounts and Family Safety” group, then click on the Credential Manager link.
Finally, if you are just looking for a listing of all of the cached credentials saved on your computer, open a Command prompt (“Windows Command Processor”) and enter the following command:
cmdkey /list
This will output an text listing of all cached credentials including the target, type and respective user name.
