Single sign-on (SSO) is a technology that allows users to log in to multiple applications or systems with just one set of login credentials. With SSO, users do not need to enter their usernames and passwords repeatedly when accessing different applications or systems, as their login information is shared across all of them.
SSO works by using a central authentication server that manages user credentials and grants access to authorized applications or systems. When a user tries to access an application, the application sends a request to the authentication server to authenticate the user. If the user has already logged in to the system, the server will provide the application with the necessary information to verify the user's identity, and the user will be granted access without having to enter their login information again.
SSO provides several benefits, including improved user experience, increased security, and reduced administrative overhead. Users do not have to remember multiple login credentials, which can simplify their login process and reduce the risk of security breaches due to weak or reused passwords. SSO also allows for better control over user access and permissions, as administrators can manage access to multiple applications from a centralized location.
