In this backend-focused project, we’ll build a production-ready authentication system from scratch using Node.js, Express, MongoDB, JWT, Google OAuth, Two-Factor Authentication (2FA) and deploy it to a real VPS (Hostinger).
What we’ll build
🔐 JWT authentication – access tokens, refresh tokens, HttpOnly cookies
🔁 Token refresh & invalidation – secure logout and password reset handling
📧 Email verification system – block unverified users from logging in
🔑 Forgot & reset password flow – secure, expiring reset tokens
🌐 Google OAuth login – social login using the same JWT infrastructure
🔐 Two-factor authentication (TOTP) – Google Authenticator / Authy support
👤 Protected routes & RBAC – user vs admin access control
🧑💼 Admin users API – list users securely (admin-only)
🧪 Postman & curl testing – test every endpoint step-by-step
🚀 VPS deployment (Hostinger) – PM2, Nginx, HTTPS, real SMTP in production
