User names and passwords entered for Office 2013 and Lync 2013 in order to log on to SharePoint Online, OneDrive, and Lync Online can be optionally saved in Windows CredMan. This typically happens when the user selects the Keep me signed-in check box. For federated user accounts, the user name and passwords are not saved. This is because Integrated Windows Authentication can be used, which does not require the password. For a third-party federated identity provider that does not support Integrated Windows Authentication, the password is not available from CredMan, and therefore it must be prompted for.
