# Apereo CAS

Essential · [Official website](https://www.apereo.org/projects/cas)

Apereo CAS (Central Authentication Service) is an open source single sign-on server maintained by the Apereo Foundation and widely used by universities. It lets users sign in once and access several web applications without logging in again. CAS relies on a ticket-granting cookie to keep the SSO session, which is strictly necessary for authentication.
