Authentication is one of the most important components of any mobile application, but implementing it securely can be challenging.
In this tutorial, you'll build a complete JWT authentication system using React Native, Node.js, Express, and MongoDB, following modern development practices and production-ready architecture.
What you'll build
- Secure user registration and login
- JWT access and refresh token authentication
- Password hashing with bcrypt
- Protected Express API routes
- React Native authentication using TypeScript
- React Navigation 7
- React Context for authentication state
- React Hook Form + Zod validation
- Axios request and response interceptors
- Automatic access token refresh
- Persistent user sessions
- Secure logout with refresh token revocation
- Production security best practices
Tech Stack
