Project goal: practical mastery of Spring Boot Security, JWT, and REST API architecture.

🔐 Auth Service API

The Auth Service API is a backend application based on Spring Boot, used to authenticate and authorize users using JWT (JSON Web Token). The project was created to teach and practically apply key Spring security mechanisms.

Project frozen - Due to the realization that I am writing a second identical application only in Spring Boot, I am moving to another project to learn more Spring Boot features.
