JWT is specified in RFC7519 Internet standard and is the most widely used authentication method in token-based authentication systems.

In this tutorial, we will implement membership registration, login, and authorization logic, and quickly and easily experience Spring Security's authentication and authorization logic.

Expected Questions Q&A 🙋🏻‍♂️

What program do you use in this course?

• I use IntelliJ IDEA, Postman, and Browser, but it's not required :)

What are authentication and authorization?

• Authentication is the process of verifying who the user sending the request is. It's the correct user.
• Authorization refers to the process of verifying whether the action the Request is trying to perform is permitted.

Please tell us what prompted you to start this course.

• I wanted to introduce a very good alternative that I found after being tired of the system expansion issues of the existing authentication method.
• As a developer, I often work on side or toy projects, and I've found myself implementing authentication and authorization using the simple JWT method. I've created this to share with you.
