Keycloak – identity and access management platform

Keycloak is an identity and access management platform for applications and services. It provides a central authentication service, allowing organisations to manage user identities without requiring every application to implement its own login and account management system.

The software supports single sign-on, identity federation and fine-grained authorisation. Applications can delegate authentication to Keycloak through standard protocols, while administrators manage identity providers, credentials, sessions and access policies from a central interface.

Keycloak is particularly suitable for organisations with multiple applications, existing user directories or complex authentication requirements. It can also serve business-to-business environments through its organisation management facilities.

This is free and open source software.
