Implementing with Spring Security and Spring Boot
Overview
This project demonstrates how to implement OAuth 2.0 authentication and authorization in a Spring Boot application using Spring Security. It showcases how to integrate third-party identity providers (like Google, GitHub, or custom Authorization Servers), handle secure token flows, and protect APIs using standardized OAuth 2.0 mechanisms.
The implementation emphasizes scalability, maintainability, and security best practices, making it a strong foundation for modern applications requiring robust user authentication.
