SSO (Single Sign-On)
An authentication scheme that allows users to log in once and access multiple related but independent applications.
Benefits of Single Sign-On
- Improved User Experience: One login for all applications
- Reduced Password Fatigue: Fewer passwords to remember
- Enhanced Security: Centralized authentication and MFA
- Simplified IT Management: Easier access provisioning and deprovisioning
SSO Protocols
Common protocols used for SSO include SAML 2.0, OAuth 2.0 with OpenID Connect, and WS-Federation.
