JWT Authentication System with HttpOnly Cookies in Django & Next.JS | Complete Project Tutorial

In this video, we'll build a secure, token-based authentication system using Django for the backend and Next.js for the frontend. We’ll cover everything from setting up a custom user model and APIs to implementing access token refresh, blacklisting, and seamless cookie-based authentication in the frontend using Axios.

⁸What We’ll do:
- Create a Custom User Model to authenticate users with email.
- Use Django REST Framework (DRF) for building APIs.
- Implement JWT-based Authentication with HTTP-only cookies using Simple JWT.
- Enable token blacklisting during logout for security.
- Set up a token refresh endpoint to automatically refresh access tokens.
- Build a responsive Next.js frontend with login, registration, and user dashboards.
- Configure Axios to handle cookies and manage user authentication seamlessly.
- Use CORS headers to securely connect the frontend and backend.

Project Features 🛠️:
- Custom User Authentication: Email-based login system with a custom user model.
- Secure Token Management: Store tokens in HTTP-only cookies to prevent XSS attacks.
- API Endpoints: Register, Login, Logout, Token Refresh, and User Info retrieval.
- Logout with Token Blacklisting: Enhance security by invalidating refresh tokens.
- Automatic Token Refresh: Refresh access tokens seamlessly in the frontend.
- Frontend Integration
