Single sign-on (SSO) is a feature offered by Crowd. Your Crowd administrator can choose to enable this feature for the Crowd-connected applications. If SSO is enabled, you will only need to log in or log out once. Specifically:

• You only need to log in once, to Crowd or a Crowd-connected application. When you start another Crowd-connected application, you will be logged in automatically.
• When you log out of Crowd or one of the Crowd-connected applications, you will be logged out of Crowd and the other application(s) at the same time.
