Keycloak: Open Source IAM Solution Managing authentication and authorization across modern applications is a complex challenge. Building these capabilities from scratch is error-prone and time-consuming. Keycloak, an open source Identity and Access Management (IAM) solution maintained by Red Hat, solves this problem by providing a robust, standards-based platform out of the box. What Is Keycloak? Keycloak is a self-hosted IAM server that centralizes authentication and authorization for your applications and services. Instead of each application implementing its own login logic, they delegate that responsibility to Keycloak. Key features include: Single Sign-On (SSO) and Single Sign-Out across applications Identity Brokering with social login (Google, GitHub, Facebook, etc.) User Federation with LDAP and Active Directory Standard protocol support: OpenID Connect, OAuth 2.0, and SAML 2.0 Fine-grained authorization with role-based and attribute-based access
