What is JWT Token | JSON Web Tokens & Stateless Authentication

jwt token authentication: Every time you log in to a modern web app, the server hands you a token. Not a traditional cookie, and not a session ID—a JSON Web Token (JWT). But how do they actually work?

In this video, we break down JWT authentication visually. You will learn the exact structure of a JSON Web Token (Header, Payload, and Signature), why stateless authentication scales infinitely better than traditional database sessions, and the critical security rules you must follow to prevent your tokens from being stolen.

Zero database calls. Just math.
