Single-Sign-On

The abbreviation Single-Sign-On, short SSO, refers to the ability to access different applications, services or data with a single authentication process. SSO, which can be translated with single sign-on, replaces the login for individual services with inter-service authentication. Each user receives in a single sign-on system an identity that can be applied to different services.

The system is responsible for confirming the user identity for various services and for ensuring that the user can access data. This saves users time and does not have to think about a new password for each application. The equivalent of single sign-on is the single sign-out, which allows users to log off from a variety of services by logging out.
