Overview
Keycloak is an open-source identity and access management platform for SSO, OAuth2, OIDC, and user management across web and mobile apps.
Pros
- Free open-source core
- Strong OIDC, OAuth2, and SAML support
- Built-in user federation and LDAP integration
- Customizable realms, clients, and flows
- Active community and broad integrations
Cons
- UI can feel dated
- Setup can be complex for non-developers
- Limited built-in MFA compared to paid IdPs
- Self-hosting requires operational overhead
Verdict
