Single Sign-On (SSO)

Single Sign-On (SSO) is an authentication mechanism that allows users to access multiple applications with a single login. It improves security and user experience by centralizing authentication and reducing password fatigue. SSO supports various protocols, including OIDC, OAuth 2.0, and SAML, enabling seamless integration across platforms. Keycloak provides robust SSO capabilities, supporting federated identity, multi-factor authentication, and session management. While SSO enhances convenience and security, it requires careful implementation to mitigate risks such as single points of failure and unauthorized access in Zero Trust environments.
