Recently, trying to use Sharepoint Designer 2013, it kept asking me to login. I just kept getting the message:
“call us overprotective, but we need to verify your account…”
Trying to run as a different user on the Computer didn’t work. Resetting Internet Explorer didn’t work. Removing credentials from the Control Panel didn’t work.
Uninstall the Windows Update: KB2768348
There were two “Update for Microsoft Office 2013” KB2768348 in the Programs and Features. Uninstalling these and rebooting sorted it 🙂
