Send 2FA Codes via SMS

Secure logins with automated SMS verification codes sent via Twilio

When users sign in, Nora generates a one-time code and sends it via SMS. Verify identity and prevent unauthorized access instantly.

Two-factor authentication via SMS is industry standard for security. When a user logs into your web app, Nora generates a 6-digit OTP (one-time password), sends it via Twilio SMS, and requires the user to enter it within 10 minutes. Nora tracks code usage (one-time only), invalidates expired codes, and logs all attempts for security audits. You can customize code length, validity period, and message text. If a user gets locked out (too many failed attempts), Nora can trigger a secondary verification (security question, backup code, etc.). Perfect for financial apps, healthcare portals, or any service requiring login security.

How it works

  1. Intercept login attempt with user phone number
  2. Generate random 6-digit OTP code
  3. Store code in temporary session with 10-minute expiry
  4. Send SMS via Twilio to user's phone with code
  5. Prompt user to enter code on verification page
  6. Validate code and log authentication attempt
