Single Sign-On (SSO) is an authentication process that allows a user to access multiple applications with one set of login credentials, across domains. Essentially, there is a central domain through which authentication is performed, and then the session is shared with other domains.
A real-world example of SSO authentication is Google’s suite of online applications. Log into a single Google application and then you are able to access other Google applications as well, thereby saving the task of reentering password every time you toggle between your Gmail Inbox and Google Drive.
Why Single Sign-on?
- Eliminates the need to manually log into each separate application thereby offers big benefits to users and administrators
- Best end user experience, and encourages end users to stay engaged with the website or apps
- Eliminates credentials re-authentication, and reducing help desk requests, thus saving costs
- Streamlines local & remote application and desktop workflow
- Improves compliance through a centralized database
