Shopify OTP Verification App for COD & Passwordless Login
Stop fake Cash on Delivery orders. Let customers log in without a password. Deliver one-time codes via SMS or email in under 30 seconds — no code required.
COD Verification
Every time a customer places a Cash on Delivery order, an OTP is sent to their phone. They verify with the code before the order ships — eliminating fake orders, wrong addresses, and costly return-to-origin shipments.
- OTP sent instantly after checkout
- Customer clicks link or enters code
- Unverified orders auto-cancelled
- Orders tagged for manual review
Passwordless Login & Signup
Replace the Shopify password form with a one-time code. Customers enter their phone number or email, receive an OTP, and are logged in or registered instantly — no password to forget or reset.
- Works on all Shopify 2.0 themes
- SMS or email channel (or both)
- Auto-creates account on first login
- Fully brandable OTP screen
