Keycloak is an open-source identity and access management solution whose core capability is Single Sign-On (SSO), enabling users to authenticate once and seamlessly access multiple cloud applications or services without repeated logins. This simplifies auth, authentication, and authorization workflows by centralizing identity verification through standards like OpenID Connect and SAML, while providing fine-grained access controls via roles, policies, and multi-factor options.

Main Features

  • OpenID Connect and SAML 2.0 Support: Enable SSO with standards-based protocols for quick integration with web apps, mobile, and APIs.
  • Multi-Factor Authentication (MFA): Add layers of security with TOTP, WebAuthn, or OTP for robust auth flows.
  • User Federation: Sync users from LDAP, Active Directory, or databases, plus social logins for hybrid authentication.
  • Fine-Grained Authorization: Role-based access control, attribute-based access control, and policies for precise permissions.
  • Admin Console & APIs: Intuitive UI for managing realms, clients, and users, with REST APIs for automation in Kubernetes or cloud environments.
  • High Availability & Scalability: Clustering, caching, and Helm chart support for production-grade deployments on your cloud infra.

Key Uses

  • Centralized SSO for SaaS Dashboards: Unify login across your user dashboard, resource tracking, and managed apps marketplace—eliminating password fatigue.
  • Microservices Auth: Secure API gateways and services with JWT tokens, perfect for TypeScript/Node.js apps using GitHub OAuth or Cloudflare Workers.
  • B2B & Enterprise Onboarding: Handle complex authorization for teams, with custom themes and branding for white-label SSO.
  • Compliance & Security: Meet GDPR, HIPAA needs with audit logs, session management, and brute-force detection.
  • DevOps Workflows: Integrate with CI/CD pipelines for automated user provisioning in Kubernetes clusters.

Keycloak turns authentication and authorization into a competitive edge, reducing login friction while boosting security and also supports auto-scaling with Karpenter for optimal resource utilization.

Deploy it as a managed app on your platform to provide enterprise-grade identity services without the hassle of self-hosting from scratch.

FAQ

  • Keycloak is an open-source Identity and Access Management (IAM) solution. Single Sign-On (SSO) allows your users to authenticate once and gain access to multiple independent applications.

  • Keycloak makes it easy to enable centralized logins .You can enable these via the admin console without writing any custom integration code.

  • By centralizing authentication, you reduce the attack surface. Instead of securing credentials across ten different apps, you secure one central point with robust features like Multi-Factor Authentication (MFA), password policies, and brute-force detection.

  • Keycloak offers powerful multi-tenancy through a feature called Realms, which act as isolated environments where you can manage specific sets of users, roles, and security policies. Within each realm, you have full control over the user experience via custom themes, allowing you to brand login, registration, and password reset pages with your own HTML and CSS. This means you can host multiple independent projects or clients on a single installation while ensuring each maintains its own unique corporate identity and data isolation.

  • Keycloak balances security and user experience through configurable session limits. The SSO Session Idle timer expires sessions after a period of inactivity, while the SSO Session Max serves as a hard limit that forces re-authentication after a set duration, regardless of activity. To maintain security behind the scenes, Keycloak issues short-lived Access Tokens that are silently updated via Refresh Tokens, ensuring users stay logged in during active work without compromising the system's integrity.
