SSO, or Single Sign-On, is an authentication process that allows users to access multiple applications with one set of login credentials. It enhances user convenience by eliminating the need to remember different usernames and passwords for each service. SSO improves security by reducing the number of times users need to log in, which lowers the risk of password-related breaches. It
is commonly used in enterprise environments to streamline access across cloud services, internal tools, and third-party applications. Technologies like SAML, OAuth, and OpenID Connect often power SSO implementations.
