## What it is
Keycloak is an open-source identity and access management service providing single sign-on, user federation, and fine-grained authorization for modern applications. It supports OpenID Connect, SAML 2.0, social login, and LDAP/Active Directory federation, managed via an admin console.

## Use cases
- add single sign-on to my applications
- self-host an identity provider with OIDC and SAML support
- integrate login with Google or other social providers
- federate authentication with LDAP or Active Directory
- centralize user management and authorization policies
- add SSO logout across multiple apps
- secure microservices with token-based authentication

## When to choose
- you need centralized SSO across multiple applications
- you want a self-hosted alternative to Auth0 or Okta
- you need OIDC, SAML, and social login behind one console
- you must federate existing LDAP/Active Directory users

## When to avoid
- you need only simple session auth in a single small app
- you cannot operate a dedicated Java-based server
- you need a fully managed identity service without infrastructure

## Facets
- artifact type: service
- maturity: stable
- function: auth, authorization, security, http-server, self-hosted
- domain: security, backend, web-development, developer-tools, self-hosted
- platform: jvm, self-hosted, cross-platform
- tags: sso, oidc, saml, identity-provider, ldap, active-directory, social-login, user-federation, cncf, single-sign-on, docker, kubernetes
