Customers sign up and log in in seconds, no passwords, no resets, no abandoned carts. Add phone OTP verification at cart and checkout to confirm real shoppers and cut fake orders, RTO and chargebacks on COD. Improved access control blocks fake signups while login logs and real-time alerts keep you updated. One-click install, mobile-first, works with every Shopify theme

My friend recommended this app to me, and I actually saw it in his store, so I decided to give it a try. It looks really useful, especially the phone OTP login and Google/Apple one-tap login, which can make the whole signup and login process much easier for customers. My store is still under development, but I’m planning to use this once we launch. I’m particularly interested in the OTP verificat...

What I appreciate is that the widget doesn't look like a third-party add-on. It picked up our theme fonts and button styles without me configuring anything. Customers have never mentioned it as feeling out of place, which is exactly what you want from something that sits on every login screen.
— Vellora
People were using virtual and VoIP numbers to bypass verification and create fake accounts. Support helped me turn on the carrier validation filter that flags non-mobile numbers. It doesn't block them outright — it just adds a second verification step. Fake account creation dropped significantly within the first week

I reached out to support because the OTP widget was overlapping with a banner on our mobile layout. They didn't just tell me to adjust my CSS — they looked at my actual store, identified the conflict, and suggested a specific fix. Response came back within a few hours on a weekday afternoon. I was genuinely impressed.
— Wajha Hub
Our B2B buyers couldn't verify with office landlines since those can't receive SMS. Support suggested enabling the email fallback option for accounts flagged as business. Now corporate buyers get a verification email instead while regular consumers still use phone. Clean separation that we didn't know the app could handle.
— Lumora
Our store is in French but the OTP popup kept defaulting to English. Support pointed me to the language pack settings — the full UI and all SMS text are translatable. They even reviewed my French translations before I published to make sure the character limits worked on mobile screens. That kind of attention to detail from a support team stands out.

We sell in a market where cash on delivery is standard and fake orders were eating into our margins. The phone verification at checkout is the single change that made the biggest difference. If someone won't verify a real phone number, they probably weren't going to answer the door either.
— Oryn
Our custom theme was pushing the OTP widget below the fold on mobile and people were missing it entirely. I reached out to support expecting a generic CSS answer. Instead they pulled up our actual storefront, identified the exact div that was causing the layout shift, and sent me a three-line code snippet. Widget moved to the right spot on the first try.

We were losing UK customers at checkout because the verification code took too long to arrive. Support looked into our account settings and found we were routed through a secondary SMS gateway for European numbers. They switched it to the direct route and response times dropped from 30+ seconds to about 5. Nobody told us there were different routing options — support just found the problem and fix...

We'd been losing customers at the account creation step for months. People would start typing a password, get the 'must include a special character and a number' prompt, and just leave. Since switching to OTP+ the drop-off at that step is basically gone. Customers type their phone number, get a code, and they're in

I’ve had a really good experience with OTP+ B2B SMS & Social Login. The app works well, and the best part is that it’s completely free. The support team, especially Arunava, has been very helpful and responsive whenever I needed assistance. Overall, a great app with excellent support. Highly recommended!

Fantastic app with a great collection of customizable sections. The Theme Editor integration is seamless, and my storefront looks much better now.
— RAZA E STORE
Excellent app and even better support! The support team was fast, clear, and really helpful in answering all my questions about pricing and setup. Highly recommend.
— Office service
We surveyed customers three months after switching to OTP+ and the feedback on the login experience was consistently positive. 'No password needed,' 'it's so quick.' When login becomes unremarkable it means it's working.
— SVELTA
The OTP widget adopted our colour scheme automatically. I didn't touch any CSS it just read the theme tokens and matched. For stores with strong brand identity that kind of invisible integration is genuinely valuable.
— TRENIQUE
An excellent solution for modern Shopify stores. Finding an OTP app that accommodates the latest platform limits was a challenge, but this app delivers perfectly. Highly recommended!
— Ekhasa
We measured login completion rate before and after OTP+. Before: significant customers who hit the login page abandoned rather than go through password reset. After: almost no drop-off at login.
