How to Add OTP Login to Your Shopify Store

If you're running a Shopify store, you've probably seen it: customers land on your site, browse products, add items to their cart — and then hit the login wall. They can't remember their password, the reset email takes too long, and they leave. That sale is gone.

OTP (One-Time Password) login fixes this. Instead of passwords, customers enter their phone number or email, get a code, and they're in. The whole process takes about 3 seconds.

Here's how to set it up on your Shopify store using Quick Login — a free app with a 5.0 rating on the Shopify App Store.

Why Add OTP Login to Shopify?

Traditional password-based login creates friction at every step:

• Forgotten passwords — The average person has 100+ online accounts. Nobody remembers them all.
• Slow reset flows — Password reset emails take time, and customers don't wait.
• Cart abandonment — Studies show that 18% of shoppers abandon carts because of account-related issues.
• Weak passwords — Customers reuse passwords, making your store a target for credential stuffing attacks.

OTP login eliminates all of these problems. Customers don't need to remember anything — they just need their phone or email inbox.

What Is OTP Login?

OTP stands for One-Time Password. It's a verification code (usually 4-6 digits) that's generated for a single login session and expires after a short time.

Here's how the flow works for your customers:

1. Enter phone number or email — Customer types their contact info on your store
2. Receive a code — A unique code is sent instantly via SMS or email
3. Enter the code — Customer types the code and they're logged in

No passwords to create, remember, or reset. It's the same flow used by WhatsApp, Telegram, and most banking apps — your customers already know how it works.

Step-by-Step Setup Guide

Step 1: Install Quick Login

Go to the Quick Login page on the Shopify App Store and click "Add app". The app is free to install.

Step 2: Approve Permissions

Shopify will ask you to approve the app's permissions. Quick Login needs access to customer accounts and your store's theme to display the login form.

Step 3: Open the App Dashboard

Once installed, open Quick Login from your Shopify admin panel. You'll see the main dashboard with options for SMS setup, email setup, and form customization.

Step 4: Configure Your OTP Method

Choose whether you want to offer SMS login, email login, or both. We recommend both — SMS for mobile shoppers and email as a fallback.

Step 5: Enable the Login Form

Choose where the OTP login form appears on your store. Options include:

• Popup — Appears as a modal overlay (most popular)
• Embedded — Placed directly on any page
• Sidebar — Slides in from the side
• Custom location — Place it anywhere using a shortcode

Step 6: Test It

Visit your store's front end, click the login button, and try the OTP flow yourself. Make sure the code arrives quickly and the login completes smoothly.

Configuring SMS & Email

SMS Setup

Quick Login supports multiple SMS providers:

• Local Israeli providers — For stores targeting the Israeli market, local SMS providers offer faster delivery and lower costs
• Twilio — For international stores, Twilio provides global SMS coverage
• Other providers — Quick Login can integrate with additional SMS gateways

Enter your SMS provider credentials in the Quick Login dashboard. The app handles all the code generation, delivery, and verification automatically.

Email OTP Setup

Email OTP works out of the box. Quick Login sends verification codes via email with no additional configuration needed. The emails are branded with your store's name and logo.

Customizing the Login Form

Quick Login's login form is fully customizable:

• Language — Built-in support for Hebrew and English. Translate to any language.
