OAuth 2.0 Fundamentals: Secure Web Application Authorization

Modern web applications require secure, seamless authentication, but building user management from scratch can be risky and complex. Implementing standard authorization protocols like OAuth 2.0 allows you to delegate security to trusted providers while offering a smooth login experience. This text-based course guides you through the core concepts of OAuth 2.0, helping you understand how authorization works behind the scenes. By reading our structured explanations and analyzing clear code snippets, you will gain the confidence to integrate secure external logins and manage API access safely. What you'll learn: - Understand the core terminology of OAuth 2.0, including clients, resource owners, and authorization servers. - Configure modern authorization flows, including the Authorization Code Flow with PKCE for enhanced security. - Implement social login integration using major identity providers to simplify user registration. - Apply OpenID Connect (OIDC) standards to handle both authentication and identity verification. - Manage access tokens, refresh tokens, and secure token storage practices to prevent common web vulnerabilities. The course starts with foundational security definitions and the architecture of delegation protocols, then transitions into step-by-step integration scenarios and modern security practices. It is designed specifically for beginners and web developers new to identity management, requiring only basic familiarity with standard web concepts like HTTP requests.
