Keycloak is an open-source identity and access management solution that provides authentication, authorization, and other security features for web applications and services. It is designed to secure applications and services by allowing users to authenticate through a variety of methods and manage access to different resources.
Keycloak is developed by Red Hat. It provides authentication and authorization services, allowing organizations to secure applications and services with features like:
Single Sign-On (SSO): Allows users to log in once and gain access to multiple applications without needing to authenticate separately for each one.
Identity Brokering and Social Login: Keycloak supports logging in using third-party identity providers such as Google, Facebook, GitHub, and others. It also integrates with standards like OpenID Connect and SAML 2.0 for identity federation.
User Federation: Keycloak can connect to existing LDAP and Active Directory services to federate user identities.
Role-Based Access Control (RBAC): Keycloak provides a fine-grained access control mechanism where roles are assigned to users or groups, determining their access level within applications.
Multifactor Authentication (MFA): Keycloak supports various authentication mechanisms, including Time-based One-Time Password (TOTP), hardware tokens, and SMS-based authentication.
Admin Console and Account Management: Administrators can manage users, roles, and groups, configure identity providers, and set up authentication policies through the admin console. Users can also manage their own accounts.
Security Features: It offers features like session management, brute force detection, and password policies to enhance security.
Keycloak can be deployed in a variety of environments, including on-premises, cloud, and containerized environments like Kubernetes and OpenShift. It’s commonly used for securing web applications, APIs, and microservices in enterprise environments.
