About This Video

Build a secure Nuxt 3 Authentication API using JWT and RSA-encrypted login with MySQL in this step-by-step tutorial.
Learn how to implement RSA encryption on the client-side to protect login credentials, and how to handle JWT authentication on the server-side for a fully secure login flow.

This video covers everything you need to create a modern, production-ready authentication system:
✔️ Setting up Nuxt 3 project and API routes
✔️ Generating RSA public/private keys
✔️ Encrypting login data on the frontend
✔️ Creating JWT tokens securely on the backend
✔️ Connecting with MySQL database
✔️ Protecting routes with JWT middleware
✔️ Handling user registration, login, and logout

Perfect for developers looking to build secure authentication systems with Nuxt 3, JWT, RSA encryption, and MySQL.
