Spring Boot and React Login Service with Social Authentication

Implementing secure user authentication is a fundamental requirement for modern web applications, yet combining backend security with a dynamic frontend can be challenging. This course guides you step-by-step through the process of building a robust login system from scratch. You will transition from understanding basic security concepts to implementing a fully functional authentication service. By reading detailed explanations and reviewing clean code snippets, you will master the connection between a Spring Boot API and a React client. What you'll learn: - Understand foundational authentication concepts, session management, and the OAuth2 protocol. - Configure Spring Boot Security to handle registration, login, and secure API endpoints. - Implement JSON Web Tokens (JWT) for stateless authentication and store them securely using HTTP-only cookies. - Integrate social login providers using OAuth2 flow on the backend. - Build a responsive React frontend to manage login state, user sessions, and protected routes. - Apply modern security best practices, including proper CORS configuration and CSRF protection. The course begins with essential security definitions and architectural overviews before guiding you through backend configurations and frontend integration. You will study complete code examples and structural walkthroughs to build a reliable, production-ready authentication flow. This course is designed for beginner to intermediate developers who want to learn how authentication works across the stack, with no advanced security experience required.
