What is Keycloak?

Keycloak is the open-source identity and access management solution. Add authentication to applications and secure services with minimum effort – no need to store or authenticate users yourself. Users authenticate with Keycloak rather than individual applications offering single-sign-on: once logged in, users access all applications without logging in again. Single-sign-out means logout once to be logged out everywhere. Features include social login (easy to add via admin console), identity brokering with OpenID Connect or SAML 2.0, LDAP/Active Directory federation, admin console for central management, and fine-grained authorization services. A CNCF incubation project.
