JWT

To implement user authentication and authorization using JSON Web Tokens (JWT) in your web application, you can follow these steps:

1. Generate a JWT when the user logs in and include relevant user information.
2. Store the JWT securely on the client-side (typically in local storage or a cookie).
3. Include the JWT in the headers of subsequent API requests.
4. Validate the JWT on the server-side to ensure its authenticity and integrity.
5. Extract the user information from the JWT and use it for authorization purposes.

JWT provides a secure way to authenticate and authorize users in web applications by using digitally signed tokens.
