Single Sign-On
Single Sign-On (SSO) is an authentication mechanism that allows users to access multiple applications or services with a single set of login credentials. It centralizes user authentication, reducing the need for separate passwords and streamlining access across integrated systems. SSO typically relies on identity providers to verify credentials and issue tokens for seamless access to connected applications.
Developers should learn SSO to implement secure and user-friendly authentication in enterprise environments, SaaS platforms, or any system requiring access to multiple services. It's essential for reducing password fatigue, improving security by centralizing authentication controls, and enabling integrations with identity providers like Okta or Azure AD. Use cases include corporate intranets, cloud service portals, and federated applications.
