If your organization uses SSO (Single Sign-on) then all users by default have the Logon Method set to “SSO”. You can change this setting for a specific user who needs to login as a “non SSO” user (i.e they need to enter a username and password to login) buy selecting “Set as Non-SSO” from the Actions (right-click) in the Contact Login grids.

You can see the Logon Method assigned to each user in the Contacts & Logins grid. The value will be either be “SSO” or “Non SSO”.
