Functional OTP Generation & Verification UI in React
🚀 Built a Fully Functional OTP Generation & Verification UI in React!
Just wrapped up an exciting project—an OTP (One-Time Password) generation and verification UI using React! It was a great learning experience, especially handling OTP input focus, paste handling, and validation seamlessly.
🔹 Key Features:
✅ Secure OTP Generation using window.crypto.getRandomValues()
✅ Auto-Focus & Smooth Input Navigation for a better UX
✅ Clipboard Paste Support for quick OTP entry
✅ Resend OTP Functionality
✅ Responsive & Mobile-Friendly Design
💡 Challenges & Learnings:
🔹 Managing controlled inputs efficiently
🔹 Using useState to handle dynamic OTP changes
🔹 Auto-focusing input fields for a seamless experience
🔹 Implementing clipboard read for OTP pasting
🔥 Security Best Practices for OTP Authentication:
✅ Use Cryptographically Secure OTPs—Frontend: window.crypto.getRandomValues(), Backend: HOTP/TOTP
✅ Limit OTP Attempts & Implement Rate-Limiting to prevent brute-force attacks
✅ Set Expiry Times for OTPs (30-60 seconds) to minimize risks
✅ Encrypt OTPs in Transit & Storage (TLS/SSL, hashing)
✅ Avoid Auto-Fill for OTPs in Emails or Messages
✅ Implement Multi-Factor Authentication (MFA) for better security
