Autenticação Segura com JWT no Node.js (Access Token + Expiration)

In this lesson, you will learn JWT (JSON Web Token) in practice using Node.js and Express. We will create an API from scratch, generate authentication tokens, protect routes with middleware, validate tokens using jwt.verify(), and understand how the complete token-based authentication flow works. Lesson content: ✓ What is JWT ✓ How to generate a token with jwt.sign() ✓ How to validate a token with jwt.verify() ✓ Authentication middleware ✓ Public and protected routes ✓ Token expiration ✓ Testing using Postman ✓ Authentication best practices If you are learning Node.js, REST APIs, or want to understand modern authentication, this lesson is for you.
