About
Keycloak is an open-source identity and access management solution that enables single sign-on, social login, and identity brokering for applications and services. It supports standard protocols including OpenID Connect, OAuth 2.0, and SAML, and integrates with existing LDAP and Active Directory servers. Administrators manage all aspects through a central admin console, while users can self-manage accounts, sessions, and two-factor authentication.
Problem
Developers need a reliable, standards-based way to add authentication and access management to applications without building it from scratch.
