Look inside
In this liveProject, you will implement an authorization server to authenticate users and issue JSON Web Tokens signed with a configured key. You'll use a Spring Boot service to take the role of an authorization server in an OAuth 2 system, set up storage for user and client details, and ensure user details persist in a secure way. Finally, you’ll write and conduct integration tests to make sure your system is secure and bug-free.
This project is designed for learning purposes and is not a complete, production-ready application or solution.
