Secure Spring Boot and React Authentication: JWT and Social Login

Building secure user authentication is a critical requirement for modern web applications, yet combining backend APIs with frontend clients can be challenging. This text-based course guides you through the process of implementing robust security using industry-standard protocols. You will transition from understanding basic security concepts to building a fully functional, secure authentication system. You will learn to handle user registration, issue secure JSON Web Tokens (JWTs), and integrate social login providers seamlessly. What you'll learn: 1. Understand the core principles of web security, JWTs, and OAuth2 protocols. 2. Configure Spring Security to protect REST APIs and manage user sessions. 3. Implement secure JWT generation, validation, and token refresh mechanisms. 4. Integrate third-party social login providers into your Spring Boot backend. 5. Build a responsive React frontend that securely stores tokens and handles protected routes. 6. Apply modern security practices such as HTTP-only cookies and CORS configuration. The course begins with foundational concepts of authentication and security architecture before moving into backend development with Spring Boot. You will then write clean React code to manage user state, resulting in a cohesive, secure full-stack application. This course is designed for beginner to intermediate developers with basic knowledge of Java and JavaScript who want to master web security. No prior security experience is required, as we start with the fundamentals. Start building secure full-stack applications today.
