The Central Authentication Service ( CAS) is a single sign-on protocol for the web. [1] Its purpose is to permit a user to access multiple applications while providing their credentials (such as user ID and password) only once. It also allows web applications to authenticate users without gaining access to a user's security credentials, such as ...

An access token is an object encapsulating the security identity of a process or thread. [2] A token is used to make security decisions and to store tamper-proof information about some system entity. While a token is generally used to represent only security information, it is capable of holding additional free-form data that can be attached ...
