I will build a professional and secure login and registration system for your website or web application. This system will include user sign-up and sign-in functionality, password hashing for enhanced security, and authentication using JSON Web Tokens (JWT). I will also implement a secure code verification process to ensure that only verified users can access your platform. The backend will be developed using Node.js and Express, and connected to a PostgreSQL or MySQL database for smooth and reliable data handling. Whether you’re building a new platform or upgrading an existing one, I will ensure your authentication system is modern, scalable, and fully secure.
