Single sign-on (SSO)

SSO centralizes the login process, letting users sign in once and then access various linked services—such as email, CRM, or HR platforms—without logging in repeatedly.

SSO uses a central authentication server (often via protocols like SAML, OAuth, or OpenID Connect). When a user logs in, the server issues a secure token that can be used across integrated applications to verify identity without asking for new credentials.

SSO improves user experience, reduces password fatigue, and strengthens security by consolidating access control. IT teams benefit from easier credential management and reduced support tickets for password resets. It also facilitates regulatory compliance through audit trails.
