Shopify's New Customer Accounts: What Enterprise Brands Need to Know Before They Switch

Shopify's New Customer Accounts: What Enterprise Brands Need to Know Before They Switch

Shopify is officially changing the way Customer Accounts work, announcing a deprecation now and future official sunset date for legacy customer accounts.

The new Customer Accounts system was rolled out in 2024, but with the Winter '26 Editions update adding extended features like social sign-in, self-service email editing, and customizable sign-in copy, the feature gap between old and new is widening fast. If your brand hasn't made the switch yet, the window where waiting makes sense is closing.

Here's what's actually changing, what you gain, what you lose, and how to think about the migration.

What's Different About the New Customer Accounts

The legacy Customer Accounts system was built on Liquid templates within your theme. You could customize them heavily, but that customization came with maintenance overhead, security responsibility, and a growing list of Shopify features that simply don't work with the old system.

The new Customer Accounts are a standalone experience managed by Shopify, separate from your theme, similar to Checkout. The trade-off is clear: you give up some of the granular Liquid-level control, and in return you get a more capable/extensible, more secure, and significantly lower-maintenance account experience.

The practical benefits for enterprise merchants and consumers are meaningful. The new Customer Account passwordless login replaces traditional credentials with a one-time verification code, which eliminates password reset friction and improves security without adding custom code. Shopify handles the authentication layer, including scaling, caching, and global performance, so your team doesn't carry that operational burden.

Beyond login, the new system unlocks features that are either difficult or impossible to implement on legacy accounts: native self-serve returns, store credit for signed-in customers, B2B wholesale access, saved payment methods, and complete order history with real-time status visibility. New Customer Accounts are also tied very closely to the Shop app features and functionality that continue to emerge and grow.

Account Extensibility Changes the Game for App Integrations

This is where the new system gets interesting for brands with complex tech stacks. Shopify's account extensibility framework tied to new Customer Accounts, lets apps add dedicated blocks and pages directly inside the customer account experience, rather than relying on theme-level Liquid customizations.

In practice, this means your subscription management (Recharge), loyalty and rewards programs (Yotpo), shipment tracking (AfterShip), and other post-purchase tools can surface natively within the customer account pages by using out-of-the-box app extensions rather than custom code. Recharge, for example, now offers a customer portal experience that lives inside Shopify's customer accounts rather than requiring a separate portal. We expect current 3rd party/app providers to begin rolling out more new features for this new functionality, along with new 3rd party/app providers to emerge. Additionally, for more custom needs, Shopify's Customer Account API will allow developers to create custom-built apps for these pages.

For brands that have built custom account page integrations over the years, this is both an opportunity and a migration consideration. The app extensibility model is cleaner and more maintainable, but your existing Liquid customizations won't carry over automatically. They'll need to be recreated using the block-based system.

The long-term upside is significant: fewer custom templates to maintain, fewer points of failure when Shopify releases updates, and a more consistent experience for customers across your entire post-purchase journey.

What You Need to Watch Out For

The migration isn't without trade-offs. A few limitations are worth evaluating before you flip the switch.

Any apps or Liquid customizations currently built into your theme's customer account pages won't transfer. You'll need to rebuild them using Shopify's block-based extensibility framework. For most brands, this is straightforward since the major apps already offer account blocks, but if you've built heavily customized account experiences, plan for the rebuild work.

Multipass authentication is not supported in the new system. If your brand relies on Multipass for SSO or cross-platform login, this is a significant consideration that may affect your migration timeline.

Workflow triggers or automations tied to legacy customer account events may not carry over. Audit your existing automations before switching.

You can't set a custom domain per market for customer account pages — only one domain applies across all markets. For multi-market brands, this means your account experience will live on a single domain regardless of market-specific storefronts.

Finally, any related account links in platforms like Klaviyo will need to be updated when you switch, since the account URL structure changes from your primary domain to a Shopify-hosted subdomain.

Winter '26 Editions: What's New

The latest Shopify Editions release adds three features that make the new customer accounts more compelling for enterprise brands.

Social sign-in. Customers can now sign in with Google or Facebook, reducing friction for first-time account creation and repeat logins. For brands in fashion, beauty, and lifestyle verticals where social login is expected, this closes a gap that's existed since the new accounts launched.

Customer-managed email addresses. Customers can now change their own email address through a one-time passcode verification flow. This is a small but meaningful reduction in support ticket volume for brands with large customer bases.

Customizable sign-in copy. You can now edit the text on your sign-in and one-time passcode pages through the theme content editor. This gives brand and marketing teams more control over the account experience without requiring developer involvement.

How This Connects to the Bigger Picture

If you're thinking about this migration in isolation, you're missing the larger opportunity. The new Customer Accounts system is one piece of a broader shift Shopify is making toward a more extensible, app-driven, and AI-ready and unified/omnichannel commerce platform.

Consider how this intersects with other priorities enterprise brands should be tracking.

AI readiness and UCP. Shopify's push toward the Universal Commerce Protocol and agentic commerce depends on clean, structured customer data. The new accounts system creates a more standardized data layer for customer identity, order history, and preferences, which is exactly the kind of structured information that AI shopping assistants need to deliver personalized recommendations and complete purchases on behalf of your customers. Brands that migrate now are building the data foundation that makes AI-driven commerce actually work.

Post-purchase experience as a conversion lever. The account experience isn't just operational infrastructure. For enterprise brands running subscriptions, loyalty programs, and repeat-purchase models, the Customer Account pages are a core touchpoint for retention and lifetime value. The new extensibility framework makes it possible to build a more cohesive post-purchase experience across rewards visibility, subscription management, order tracking, and self-serve returns in one place. All without the maintenance burden of custom Liquid code.

Migration complexity for brands coming from SFCC or other platforms. If you're migrating to Shopify from Salesforce Commerce Cloud or another enterprise platform, the customer account system is one of many decisions you'll need to make during the build. Starting with the new accounts from day one avoids the double migration (legacy then new) that brands already on Shopify are facing. It's one less thing to rebuild later.

Managed services and ongoing optimization. For brands already working with a Shopify partner on managed services, the account migration is a natural sprint item — scoped, testable, and lower-risk when handled as part of an existing engagement. The app block rebuild work, domain updates, automation audits, and testing are exactly the kind of well-defined implementation tasks that benefit from structured delivery.

How to Approach the Migration

The migration itself is not technically complex, but it does require methodical execution. Here's the sequence we recommend.

Start by auditing your current account customizations. Identify any Liquid-based customizations, app integrations, or workflow automations that are tied to legacy accounts. Most of these will have block-based equivalents in the new system, but you need the full picture before you switch.

Duplicate your existing checkout and accounts configuration. Shopify lets you create a draft version of customer accounts to preview and customize before publishing. Use this to build out your new account experience, including app extensions for subscriptions, loyalty, tracking, and other tools without touching your live setup.

Update your branding. The checkout style branding you've configured applies to customer accounts as well. Make sure the visual experience is consistent with your brand standards.

Verify your sender email. The new passwordless login depends on customers receiving one-time passcode emails. Confirm that your sender address is properly configured and deliverable.

Plan for the domain change. Your customer account URL will move from your primary domain to a Shopify-hosted subdomain. Update any account links in email templates, Klaviyo flows, support documentation, and transactional communications.

Test before you switch. Log in as a customer. Test the one-time passcode flow. Verify that app blocks are rendering correctly. Check order history, subscription management, and returns. Then publish.

The Bottom Line

Shopify's new Customer Accounts aren't optional for much longer. We recommend brands begin planning for migration now, ahead of an official sunset announcement, to unlock all of the future platform capabilities that Shopify continues to release — B2B, AI commerce, extensibility, self-serve returns. Legacy accounts will work until they don't, and by then you'll be migrating under pressure instead of on your own timeline.
