What is Single Sign-On (SSO)?


Single Sign-On (SSO) is a web authentication system that allows you to log in with your Active Directory, Business Systems, or Student SSO account in one application and then access another application without having to enter the same credentials again.  Once logged in to one application, you can navigate to other Single Sign-On applications which use the same account system without needing to log in again.

Without Single Sign-On, you would need to enter a username and password each time you went to a new UC San Diego tool or application.
