External Authenticators


Single sign-on (SSO) is a element of access control of multiple related, yet independent, software systems. A user logs in with a single ID and password to gain access to a system without using different usernames or passwords, or in some configurations seamlessly sign on at each system.

Benefits of using single sign-on include:

    Mitigate risk for access to 3rd-party sites (user passwords not stored or managed externally)
    Reduce password fatigue from different user name and password combinations
    Reduce time spent re-entering passwords for the same identity
    Reduce IT costs due to lower number of IT help desk calls about passwords

SSO shares centralized authentication servers that all other applications and systems use for authentication purposes and combines this with techniques to ensure that users do not have to actively enter their credentials more than once.
