SSO: Single Sign On or Signon

In any client/server relationship, single signon (or sign on, SSO) is a session/user authentication process that permits a user to enter one name and password in order to access multiple applications. The single signon, which is requested at the initiation of the session, authenticates the user to access all the applications they have been given the rights to on the server, and eliminates future authentication prompts when the user switches applications during that particular session.
