Shopify Legacy Customer Accounts Are Being Retired

If you've seen a banner about "legacy customer accounts" in your Shopify admin panel, don't ignore it. As of February 2026, Shopify has officially deprecated its old customer accounts system. This change directly affects new stores, existing stores, and customized account pages. In this guide, we've explained what's changing, how to make the transition, and what to watch out for — from the Byte perspective.

What Are Legacy Customer Accounts and What Happened in Shopify?

"Legacy customer accounts" refers to Shopify's older account system where customers sign in with an email address and password. This system runs on Liquid template files such as customers/login.liquid and is tightly coupled to the theme code.

Shopify has removed this system as of February 2026. What does this mean?

New Shopify stores can no longer use legacy accounts. Existing Shopify stores continue to work for now, but Shopify will not add new features or provide technical support for this system. A definitive "sunset" (shutdown) date will be announced within 2026; after that date, legacy accounts will stop working entirely.

Key Differences Between Shopify Legacy and New Customer Accounts

While the new generation of Shopify accounts offers many advantages, it does contain some structural differences from the current system. We recommend reviewing the existing limitations to avoid issues down the line.

The new system in Shopify isn't just an update — it's an entirely different architecture designed for modern e-commerce.

Why Is Shopify Making This Change?

Shopify has concrete reasons for taking this step, both from a security and technical sustainability standpoint:

• Password-based login creates security vulnerabilities. Customers forget their passwords, submit support tickets, or abandon the login page entirely. Passwordless sign-in with a 6-digit verification code eliminates all of these problems.

• Liquid templates are fragile. Customizations can break during Shopify theme updates. Since every app is forced to inject code into these templates, security risks also increase.

• The new architecture is extensible. The new account system is built on Shopify's app extensions platform. Features like store credit and self-serve returns can be used without requiring theme updates.

Limitations to Know Before Switching to the New System in Shopify

While the new system in Shopify is better in almost every way, keep the following points in mind before making the transition:

• Custom sign-in experiences: Shopify legacy URLs such as /account/login are automatically redirected to the new system. If you've built a custom login modal or page, you'll need to remove that code from your theme before upgrading.

• Shopify Flow automations: Workflows and triggers tied to legacy customer accounts cannot be migrated to the new system — they need to be rebuilt.

• Customer segments: Segments using the customer_account_status filter won't work correctly after upgrading, as this filter is exclusive to the legacy system.

• Multipass: Multipass is not supported on the new Shopify customer accounts. An OAuth 2.0 + OIDC identity provider can be used as an alternative.

• Sign-in page customization: App blocks cannot be added to the sign-in page; customization is only possible on pages after authentication.

• Revert window: You can return to the old system within 30 days of upgrading. After this period, the change is permanent.

How to Switch to New Customer Accounts in Shopify: Step by Step

The steps you need to take to make the transition to new customer accounts on Shopify seamless are as follows:

1. Audit Your Existing Shopify Legacy Customizations

Go to Shopify Admin > Online Store > Themes > Edit theme. From the Home page dropdown menu, select Legacy customer accounts. Review each template — customer account, login, register, addresses, order — and note any custom links, loyalty program integrations, and code changes.

Then go to Online Store > Themes > Edit code and review every file in the templates > customers folder. This step helps you identify which features will need to be rebuilt using apps during the transition.

2. Back Up Your Checkout Configuration

Go to Settings > Checkout in Shopify and duplicate your active configuration. Working on this copy allows you to set up the new experience without affecting your live Shopify store.

3. Replace Legacy Customizations with Apps

For each customization identified in step 1, find an app alternative. Features like loyalty programs, wishlists, and returns management can be integrated into the new account system via apps from the Shopify App Store. To add app blocks, go to Settings > Checkout > Customize and open the Apps tab.

4. Update Your Brand Settings

In Shopify, checkout and customer accounts share the same brand settings. Go to Settings > Checkout > Customize > Settings to verify your logo, colors, and typography.

5. Connect a Subdomain

Using a subdomain such as account.yourstore.com for customer account pages is important for a professional appearance. You can configure this in Settings > Domains.

6. Verify Your Sender Email

In Shopify, the new passwordless sign-in system sends verification codes via your sender email address. Go to Settings > Notifications to check your sender address and make sure you have active access to it.

7. Publish Your Configuration and Upgrade

Once preparations are complete, publish the duplicated configuration from Settings > Checkout (Publish). As the final step, click the Upgrade button on the Settings > Customer accounts page. After the upgrade is complete, you have 30 days to revert to the old system if needed.
