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 over SMS is widely used because it needs nothing more than a phone number. 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.
Runs real-time on login attempts using Twilio, run by your Operations Manager.
