🔐 Understanding JWT (JSON Web Tokens) 🔐

JSON Web Tokens (JWT) are an important part of modern web security, making it easier to handle user authentication.

Here’s a quick breakdown:

📜 What is JSON?
JSON (JavaScript Object Notation) is a format used to store data in key-value pairs, commonly used for web applications.

🏗 Structure of JWT:
1. Header: Contains metadata about the token (e.g., algorithm, token type).
2. Payload : Holds user information (e.g., user gD, username).
3. Signature : Ensures the token’s validity.

🔑 JWT Authentication Process :
1. User logs in and receives a JWT.
2. The client sends the JWT with each request to access protected resources.
3. The server validates the token’s signature and checks if it’s expired.
4. If valid, access is granted; otherwise, an error is returned.

JWT helps secure communication between the client and server without needing to repeatedly check credentials, making it both efficient and secure.
