Keycloak

Keycloak is an open-source identity and access management (IAM) system developed by Red Hat. It provides robust authentication, authorization, and security capabilities for web and mobile applications. Keycloak allows organizations to secure their applications and services by centralizing user authentication, role-based access control, single sign-on (SSO), and social login integration. It supports various identity standards, including OpenID Connect, OAuth 2.0, SAML, and more, making it a versatile solution for managing user identities and securing resources. Keycloak is highly customizable, extensible, and can be integrated with a wide range of platforms and services, making it a popular choice for enhancing the security and user management of applications.
