JWT Token Explained | What is JSON Web Token

In this video, I explain what JSON Web Tokens (JWTs) are, how they work, and why they’re so widely used in modern applications. You’ll learn the difference between JWT and traditional session-based authentication, see the structure of a JWT (header, payload, signature), and understand where JWTs fit best in real-world systems like microservices and distributed apps. Perfect for developers who want a clear and practical explanation of JWT.
