Shopify Legacy Customer Accounts Are Deprecated — What It Means for Your Store
February 2026 brought a significant change from Shopify. Here’s what every merchant needs to know — and what to do about it.
What’s Changed?
Shopify has officially deprecated its legacy customer accounts system. As of February 26, 2026, legacy customer accounts are no longer available to new stores, and existing stores that haven’t yet adopted the newer version will no longer receive feature updates or technical support. A final sunset date — at which point the legacy system will be switched off entirely — is expected to be announced later in 2026. If your store is currently using legacy customer accounts, this affects you directly.
Legacy vs. New: What’s Actually Different?
The distinction here goes beyond a cosmetic refresh. Shopify’s new customer accounts represent a
fundamental rethinking of how customers authenticate and interact with your store.
Authentication
Legacy accounts rely on traditional email-and-password logins — a model that consistently generates friction. Forgotten passwords, locked-out customers, and the resulting support tickets are a known cost of doing business under the old system.
New customer accounts replace this entirely with passwordless sign-in. Customers enter their email address and receive a one-time code. It’s faster, more secure, and significantly reduces the “I can’t log in” support burden that plagues so many DTC brands.
Built-in Features
The new accounts system comes with native support for store credit, self-serve returns, and B2B functionality — all without requiring custom development. Critically, these features update automatically as Shopify ships improvements. Your team benefits from new capabilities without lifting a finger. Under the legacy system, merchants often needed custom development work or third-party apps to achieve equivalent functionality — introducing cost, complexity, and ongoing maintenance overhead.
No-Code Customisation
New customer accounts support app blocks — a no-code way to customise both functionality and appearance directly from the visual editor. These customisations are upgrade-safe, meaning they won’t break when Shopify pushes updates. For brands that want control over their post-purchase experience without a development dependency, this is a significant quality-of-life improvement.
Why You Shouldn’t Wait
The temptation when facing a deprecation notice is to defer. After all, your existing setup still works — at least for now. But the risks of waiting compound over time.
No more bug fixes or security updates. Legacy accounts are now in maintenance mode at best. Any vulnerabilities that emerge will not be patched.
You’ll be migrating under pressure. When Shopify announces the final sunset date, merchants who haven’t yet migrated will face a race against time. Rushed migrations during peak trading periods are a recipe for disruption.
You’re missing out now. Every day on the legacy system is a day without the improved sign-in experience, native returns handling, and automatic feature updates that competitors on new accounts are already benefiting from.
How to Get Started
Shopify has published a comprehensive upgrade guide via the Shopify Help Centre. For merchants with straightforward setups and minimal customisation on their existing accounts pages, the migration can be relatively painless. Where it gets more complex is when legacy accounts pages have been customised — custom Liquid code, bespoke login flows, integrations with loyalty programmes or CRM platforms. In these cases, a careful audit before migration is essential to ensure nothing is lost or broken in the process.
How Bounce Can Help
At Bounce, we work exclusively with Shopify — and migrations like this are exactly the kind of work we do well. We’ll audit your existing customer account setup, identify any custom code or third-party dependencies that need to be addressed, and manage the end-to-end migration.
That means your store makes the transition cleanly, your customers notice an improvement, and your team doesn’t have to worry about what’s been left behind. Whether you’re a growing DTC brand, a luxury retailer, or a business operating in the B2B space, we’ll make sure the upgrade works for your specific setup.
