Not a marketing suite
It sends transactional messages on channels it already holds a consent for. Campaign sending, segmentation and flows belong in your ESP.

Simply OTP Login & Notify
Simply OTP Login & Notify replaces the password on a Shopify storefront with a one-time code sent by SMS, WhatsApp or email, and uses the same delivery channels to send order and abandoned-cart notifications. It is free to install, carries the Built for Shopify badge, and is rated 4.7 from 76 reviews on the Shopify App Store.
IN SHORT
- Customers sign in with a one-time code sent by SMS, WhatsApp or email instead of a password.
- The same channels carry transactional notifications — order status and abandoned cart — so you are not paying two vendors for one phone number.
- The login widget is configured in the theme editor, not in code.
- B2B company registration with automated approval rules is a $10/month add-on on the Basic and Premium plans.
- Free to install. Paid plans are $4.99 and $19.99 a month, both with a seven-day trial, plus usage charges for the codes themselves.
What it does
A password is a thing your customer has forgotten. On a storefront where someone buys twice a year, the reset email is a bigger part of the login experience than the login is — and every step of that flow is somewhere the order can be abandoned.
This app removes it. The customer enters a phone number or an email, receives a one-time code by SMS, WhatsApp or email, and is in. Because the app already holds a verified phone number and a delivery channel, it also sends the transactional messages you would otherwise buy a second tool for: order status and abandoned cart.
The widget is placed and styled in the theme editor, and every code and notification is logged with a delivery report, which is the part that matters the first time a customer says they never got the message.

What it is not
Not free to run
The app is free to install; the codes are not. Model your OTP volume against your gateway rate before you compare plan prices.
Not a fraud tool
A one-time code proves someone controls a phone number. It is not device fingerprinting, velocity checks or chargeback defence.
Not always necessary
Shopify’s own customer accounts already do email one-time codes. If phone, WhatsApp, B2B approval and notifications are all irrelevant to you, use the native flow.
Login questions
Does OTP login replace Shopify customer accounts?
No — it sits on top of them. Shopify’s new customer accounts already use one-time codes by email; this app adds phone and WhatsApp as delivery channels, a widget you can place and style yourself, delivery logs, and the notification side. The customer record stays a Shopify customer record.
What does OTP delivery cost?
The plan price does not include the codes. Usage-based charges apply for OTP and notifications on the default services, and the free and paid plans all cover up to 100,000 customers with $5 per additional 100,000. If you already have an account with one of the supported gateways you can connect it and pay that provider directly instead.
Which SMS and WhatsApp providers does it work with?
Firebase, Infobip, MSG91, Gupshup, TrustSignal, Connect Saudi, MagtiCom and OTP Plus, across phone, email and WhatsApp. Bringing your own gateway is the usual reason to pick Premium, which adds sender ID and template customization.
Can we collect marketing consent during login?
Yes. There is an email opt-in checkbox you can add to the OTP login step. Treat it as consent capture with everything that implies — it needs to be unticked by default and recorded, the same as any other opt-in.
Is it fast enough to put on the critical path?
It carries Shopify’s Built for Shopify badge, which is assessed partly on performance and can be withdrawn. That is a stronger signal than anything we could claim ourselves, but it is not a substitute for checking your own Core Web Vitals after install — which is true of every app you add.
NEXT STEP
Need it to behave differently?
The B2B approval rules and the gateway integrations exist because merchants asked. If your login flow has a wrinkle the app does not cover, tell us what it is.
