You should have basic Java knowledge and understand Spring Boot fundamentals like REST controllers, services, and dependency injection. Familiarity with Maven and basic database concepts is helpful but not required. We'll guide you through everything else, including Docker setup and PostgreSQL configuration.

No! We start from the basics and progressively build your understanding. The course is designed for developers who haven't worked with Spring Security before. We explain authentication flows, security configurations, and JWT concepts from the ground up before implementing them.

This course uses Spring Boot 3 and Spring Security 6, the latest versions as of 2024-2025. All code follows current best practices and deprecation updates, so you're learning the modern approach to Spring Boot security, not outdated patterns.

Absolutely. JWT authentication with Spring Security is one of the most common interview topics for backend Java positions. You'll gain hands-on experience with token-based authentication, role-based authorization, password encoding, and REST API security—all concepts that frequently appear in technical interviews.

You'll work with Spring Boot 3, Spring Security 6, JWT (JSON Web Tokens), PostgreSQL, Docker, Spring Data JPA, BCrypt password encryption, RestAssured for testing, and Maven for dependency management. These are industry-standard tools used in production applications.

Yes! While we use PostgreSQL in the course, the JPA implementation works with any relational database. You can easily switch to MySQL, H2, or other databases by changing the driver dependency and connection properties. The Spring Security and JWT code remains identical.

Most tutorials just give you code to copy without explaining why it works. This course teaches you the fundamentals first—how Spring Security processes requests, how JWT tokens are structured and validated, and why we implement things a certain way. You'll understand the architecture, not just memorize code.

Yes! JWT authentication is perfect for microservices because it's stateless and scalable. The patterns you learn here apply directly to microservices, mobile backends, and any distributed system that needs secure API authentication. We cover the same JWT implementation used in production microservices.

Yes, you'll have access to all the source code. We build the project step-by-step throughout the course, and you'll receive the complete GitHub repository with all modules, configurations, and implementations.

The course is designed to be completed at your own pace. Most students finish in 6-10 hours, depending on how much time you spend practicing and experimenting with the code. All modules are structured so you can learn one concept at a time without feeling overwhelmed.

Definitely. By the end, you'll have built a complete authentication system from scratch and understand every component. You'll know how to generate JWT tokens, validate them, implement role-based access control, and secure REST endpoints. You can take this knowledge and apply it to any Spring Boot project.

You can ask questions in the course Discord community, and we're committed to helping you succeed. Many common issues are also addressed throughout the course modules, especially around JWT configuration, Spring Security setup, and database connectivity.
