keycloak
Alternative to Auth0
Keycloak is a platform for single sign-on (SSO), identity management, and access control. Supporting OIDC, SAML 2.0, and LDAP, it centralizes authentication and authorization for applications.
- Single sign-on via OIDC and SAML 2.0 for unified authentication across multiple apps
- Identity brokering integrating GitHub, Google, Facebook, and other social logins
- User federation with LDAP and Active Directory integration
- Admin console for managing users, roles, clients, and realms
- Fine-grained authorization with resource-based access control policies
- Multi-factor authentication with OTP, WebAuthn/FIDO2, and custom auth flows
Built in Java on Quarkus and led by Red Hat, Keycloak is the de facto standard for self-hosted enterprise authentication infrastructure as an alternative to Auth0 and Okta.
