What are the best practices for implementing JWT authentication in a Django backend?

When implementing JWT authentication in Django, consider the following best practices: 1. Use a strong secret key for signing tokens. 2. Set appropriate expiration times for tokens. 3. Use HTTPS to protect token transmission. 4. Implement token blacklisting for logout functionality. 5. Validate tokens on every request.

How can I securely store the JWT secret key?

You should store the JWT secret key in environment variables or a secure vault service, rather than hardcoding it in your codebase.

What libraries can I use for JWT in Django?

Popular libraries for JWT in Django include Django REST Framework JWT, SimpleJWT, and Auth0's JWT library. Each has its own features and benefits.

Can you explain how token expiration works?

Token expiration is set when the token is created. After the specified time, the token becomes invalid, requiring the user to log in again to receive a new token.
