Understanding JSON Web Tokens
Explore what JWTs are, their benefits for modern web applications, and their role in authentication and authorization.
What are JSON Web Tokens?
Welcome! Today, we'll explore JSON Web Tokens (JWTs). A JWT is a compact, URL-safe string used to securely transmit information between parties.
Think of it as a digital ID card for your application users.
Why Use JWTs?
Traditionally, web applications used server-side sessions. This meant the server had to store user session data.
JWTs offer a stateless alternative. The token itself contains all the necessary user information, removing the need for the server to store session data.
