What is Single sign-on? A short definition.

Single sign-on (SSO) is a method of authentication that allows a user to access multiple applications or websites with a single set of login credentials.

Instead of remembering multiple sets of username and password combinations, the user only needs to enter their login information once to gain access to all of the connected systems.

This can improve user convenience and security by reducing the risk of password reuse and simplifying the process of accessing protected resources.
