Getting Started with SSO single sign-on

1,Introduction to SSO

SSO (single sign-on) is part of identity management. A more popular definition of SSO is that SSO refers to the same user who accesses a protected resource in a different application in the same server and only needs to log in once, that is, after security authentication in one app, and then access to protected resources in other apps, no re-login verification is required.

SSO and Identity management software background

In the current enterprise application environment, there are often many application systems, such as office automation (OA) system, financial management system, file management system, Information Inquiry system and so on. These application systems serve the information construction of enterprises and bring good benefits to enterprises. However, it is not convenient for users to use these applications. Every time the user uses the system, they must enter the user name and user password for authentication, and the application system, user account is different, users must remember multiple sets of user name and user password. Especially for enterprises with a large number of application systems and a large number of users, this problem is particularly prominent. The cause of the problem is not the system development error, but the lack of overall planning, the lack of a unified user login platform.
