What is Single Sign-On (SSO)?

Single sign-on (SSO) is a property of access control of multiple related, but independent software systems. With this property, a User logs in once and gains access to all systems without being prompted to log in again at each of them. Conversely, Single sign-off is the property whereby a single action of signing out terminates access to multiple software systems.


As different applications and resources support different authentication mechanisms, single sign-on has to internally translate to and store different credentials compared to what is used for initial authentication.


Benefits

Benefits of using single sign-on include:


  • Reducing password fatigue from different user name and password combinations
  • Reducing time spent re-entering passwords for the same identity
  • Reducing 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.


SSO users do not need to remember so many passwords to log in to different systems or applications.
