Keycloak Foundations: Managing Authentication with OAuth 2.0 and OpenID Connect

Securing modern applications requires robust identity and access management, but building authentication from scratch is complex and risky. Keycloak provides an open-source, industry-standard solution to handle user login, registration, and security protocols seamlessly. This text-based course guides you through the core concepts of Identity and Access Management (IAM) using Keycloak. You will understand how to set up, configure, and integrate Keycloak to protect your services and manage user permissions effectively. What you'll learn: - Understand foundational IAM concepts, including the differences between authentication and authorization. - Configure Keycloak realms, clients, users, and roles to manage access control. - Apply OAuth 2.0 and OpenID Connect protocols to secure web applications. - Implement modern security practices such as PKCE for enhanced client-side protection. - Explore single sign-on workflows to streamline user login across multiple services. - Analyze token-based security and learn how to validate JSON Web Tokens safely. You will start with essential terminology and structural setup before moving on to practical configuration scenarios. The lessons walk you through step-by-step written explanations and configuration examples to build a secure authentication flow. This course is designed for beginner developers, system administrators, and security enthusiasts who want to learn access management without prior Keycloak experience.
