In this in-depth tutorial, we’ll create a secure authentication system from front to back, combining Two-Factor Authentication (2FA), session management, and a seamless user experience.
🔐 What You’ll Learn:
✔ Frontend (React): Build a clean login &amp; 2FA verification flow
✔ Backend (Node.js &amp; Express): Secure API routes &amp; handle sessions
✔ Passport.js: Implement local strategy for email/password auth
✔ Speakeasy: Generate &amp; verify Time-Based OTPs (TOTP)
✔ QR Code Setup: Allow users to enroll in 2FA via authenticator apps (Google Authenticator, Authy, etc.)
✔ Session Management: Keep users logged in securely
