If you’ve used Netflix, Facebook, or any online service, you’ve probably been using JWTs without even realizing it. But what is JWT, and why is it everywhere?

Let’s break it down super simple, so even if you have zero technical knowledge, you’ll understand it by the end of this article!

📌 What is JWT? (In the Easiest Way Possible!)

Imagine you go to a VIP party, and the bouncer at the entrance gives you a stamp on your hand after checking your ticket.

🔹 That stamp = Your JWT token
🔹 The party = The website or app you are using
🔹 The bouncer = The authentication system

Once you have the stamp, you don’t need to show your ticket again every time you go in and out of the party.

Similarly, a JWT token is like a digital stamp that proves who you are without making you log in again and again.
