Have you ever encountered Keycloak as a component of architecture?

Yes, I have worked with Keycloak as a component of architecture for managing user authentication and authorization.

Keycloak allows centralized management of users, roles, and access rights, and supports protocols such as OAuth2, OpenID Connect, and SAML.

In one project, Keycloak was used for single sign-on (SSO) across multiple services, which greatly simplified security management and improved user experience.

Integration with applications was done through adapters or standard protocols, enabling quick and reliable implementation of API and UI security.
