Keycloak is an open-source IAM solution developed by Red Hat, offering authentication, authorization, SSO, social login, and user federation.
It is self-hosted, flexible, and powerful, similar to Auth0 or Firebase Auth.
Keycloak simplifies user, permissions, and roles management for web apps, mobile apps, or APIs.
Setting up Keycloak can be done using Docker or manual installation.
After installation, one can log in to the Keycloak Admin Console at http://localhost:8080 with admin/admin credentials.
Keycloak revolves around concepts like realms, clients, users, roles, and groups for configuration and security.
It supports OAuth2 and OpenID Connect by default.
Keycloak can be integrated with frontend applications for user authentication using various libraries like keycloak-js, react-keycloak, or passport-keycloak.
For apps requiring login and role-based access control, Keycloak is a valuable addition to the tech stack saving development time and supporting modern protocols.
Keycloak is an open-source tool that scales with the needs of developers.
