What are JWTs and how do you use them?

JWT (JSON Web Token) is a compact, URL-safe token used for securely transmitting

information.

• Consists of Header, Payload, and Signature
• Used to verify user identity and permissions

📌 Generate:

const jwt = require('jsonwebtoken');

const token = jwt.sign({ id: user.id }, 'secret', { expiresIn: '1h'

});

📌 Verify:

jwt.verify(token, 'secret');
