How does JWT authentication work in Django REST Framework?

JWT (JSON Web Token) authentication allows you to securely transmit information between parties as a JSON object. In Django REST Framework, it involves generating a token upon user login, which is then used for subsequent requests.

What are the benefits of using JWT over traditional session authentication?

JWTs are stateless, meaning they don't require server-side storage, making them scalable. They also allow for cross-domain authentication and can carry more information.

Can you explain how to implement JWT authentication in a Django project?

Sure! First, install the djangorestframework-simplejwt package. Then, add it to your INSTALLED_APPS, and configure your settings to use JWT authentication.

What should I do if my JWT token expires?

You can implement a refresh token mechanism that allows users to obtain a new access token using a valid refresh token.
