What OTP+ actually does
OTP+ replaces password friction with phone-number OTP login over SMS and one-tap Google and Apple social login, so customers sign in or sign up in seconds. The easier the login, the more accounts you capture, which feeds repeat purchases and marketing.
The other half is fraud defense. OTP verification at checkout confirms a real, reachable phone number, which cuts fake and COD orders, return-to-origin, and chargebacks. Detailed login logs and browser bot-detection alerts show you what is being caught, and the widget is customizable and mobile-first.

Frequently asked questions
What does OTP+ do?
It adds passwordless phone-OTP login and one-tap Google/Apple social login, plus OTP verification at checkout. The login side reduces friction and grows signups; the checkout side verifies phone numbers to cut fake and COD orders, RTO, and chargebacks.
Is OTP+ really free?
Yes, the app is free. The one thing to check is SMS: OTP delivery usually goes over SMS, so confirm any sending costs or regional coverage limits during setup and on the Shopify listing.
How does it reduce COD and RTO losses?
By requiring an OTP at checkout, it confirms the customer’s phone number is real and reachable, which filters out fake or careless COD orders that otherwise turn into return-to-origin and lost shipping costs.
Will it work with my existing accounts?
It is designed to sit alongside Shopify customer accounts, but every store’s setup differs. Test login and checkout flows end to end during the trial to confirm it fits your accounts and theme.
Is the small review count a problem?
It is worth noting: 4.8 across 12 reviews is positive but a small sample. Since the app is free, the simplest path is to trial it on your own funnel and judge it on your results rather than the review count alone.
Who benefits most from OTP+?
Stores in COD-heavy markets fighting fake orders and RTO get the most value, followed by any store that wants faster, passwordless login to lift signups. Prepaid-only stores with no fraud issue will benefit less.
