SSO, or Single Sign-On, refers to a method of authentication where a user is able to access multiple systems or applications by logging in only once. It is a centralized system that allows users to have one set of credentials (such as a username and password) to access various resources, eliminating the need for multiple logins.
With SSO, a user can log in to a primary application or system, known as the identity provider, and then gain access to multiple linked applications or services without the need to enter separate login credentials for each one. This is achieved through the use of authentication protocols such as Security Assertion Markup Language (SAML) or OpenID Connect.
The primary benefit of SSO is enhanced usability and convenience. Users no longer need to remember multiple usernames and passwords, which can be a source of frustration and security risks. SSO also simplifies administrative tasks, as user account management is centralized, making it easier to grant or revoke access to multiple applications in one place.
In addition to user convenience, SSO improves security by reducing the chances of weak passwords or account lockouts due to forgotten logins. It also allows for better monitoring and auditing of user activity across different applications, aiding in regulatory compliance efforts.
Overall, SSO is a method of authentication that offers convenience, improved security, and streamlined user management by providing a single login for multiple systems or applications.
