What is Single Sign-On

Single Sign-On (SSO) refers to the process where a user only needs to enter their username and password once. After completing authentication and logging into one application, they can directly access all application systems. From this, it can be seen that Single Sign-On goes a step further than unified authentication. While allowing all application systems to be accessed using a single set of user credentials, it also enables users to log in only once to one application, eliminating the need to re-enter the same credentials when accessing other applications.
