Legacy Customer Accounts Are Dead (And the Clock Is Ticking)
Shopify has officially deprecated legacy customer accounts. As of February 2026, the old email-and-password login system is done. No more feature updates. No more technical support. New stores can't even enable it anymore.
The exact date when legacy accounts stop working entirely hasn't been announced, but it's coming later in 2026. When that sunset date hits, every store still running legacy accounts will have their login flows and account pages switched off.
Your custom login page? Gone. Your Liquid account templates? Gone. The password-based system your customers have been using for years? Replaced, ready or not.
Here's why waiting is risky: Shopify gives you a 30-day revert window right now. Migrate today, and if something breaks, you can roll back. Wait until the forced cutover? No safety net. No rollback. No support.
What are Legacy Customer Accounts?
If you've run a Shopify store for any length of time, you know the drill. Customers register with an email and password, sign in the traditional way, and manage their account through pages you could customize in your theme code.
For years, this worked. But the cracks were always there:
- Password resets are the #1 support ticket: Customers forget passwords constantly. Every reset is friction. Every friction point costs conversions.
- Theme customizations are fragile: The old account pages are built with Liquid (Shopify's template language). Every theme update risks breaking your custom work.
- Missing modern features: Store credit, self-serve returns, B2B management, subscription dashboards: none of these work with the old system.
- Security gaps: Password-based login is less secure. Credential stuffing, phishing, and password reuse are real threats that passwordless login eliminates.
Shopify spent over two years building the replacement. Now they're making the switch mandatory.Read More: Customer accounts and legacy customer accounts
What's Replacing Them, New Customer Accounts?
The new system is a ground-up rebuild. The headline feature: passwordless login. Customers enter their email, get a one-time 6-digit code, and they're in. No password to remember. No password to reset.
But that's just the start:
- Passwordless authentication: Email + one-time code. Customers can also use Shop App credentials, passkeys, or social login (Google, Facebook).
- No registration required: Customers enter their email. If they've ordered before, they're recognized automatically. No forms to fill out.
- Self-serve returns: Customers start returns directly from their account dashboard.
- Built-in store credit: Customers see their balance and apply it at checkout automatically.
- B2B and DTC in one system: One account system handles both business and consumer customers.
- 800+ app extensions: Loyalty programs, wishlists, custom forms, all installable without writing code.
For Shopify Plus merchants: you can connect your own identity provider (think services like Auth0 or Okta, these are tools that manage how customers sign in across multiple platforms) to replace the default sign-in for full single sign-on.
Legacy vs. New Customer Accounts, Side by Side
| Feature | Legacy | New |
|---|---|---|
| Sign-in | Email + password | Passwordless (email + code) |
| Registration | Form + password required | Not required (auto-recognition) |
| Customization | Liquid templates in theme | No-code editor + app extensions |
| Self-serve returns | Not supported | Built-in |
| Store credit | Not supported | Native |
| B2B support | Consumer-only | B2B + consumer unified |
| Single sign-on | Multipass (being retired) | Modern identity providers |
| App ecosystem | Limited | 800+ extensions |
| Shopify support | Deprecated, no updates | Active development |
The Migration Timeline
- February 2026: Deprecated. Not available for new stores. No more updates.
- Now (March–April 2026): Still works on existing stores, but unsupported. If something breaks, you're on your own.
- Later in 2026 (TBA): Final sunset. Everything stops.
The detail most merchants miss: Shopify gives you a 30-day revert window when you switch. Migrate now, test everything, and if something's wrong, flip back. Once the hard deadline hits, that option vanishes.
Existing stores aren't being cut off overnight. You have breathing room, but it's shrinking. Use this window for a controlled, tested migration rather than a panicked last-minute switch.
Who This Hits Hardest?
Not every store faces the same level of effort. Here's how different store types are affected, with practical examples:
Simple Stores with Minimal Customization
Close to a same-day fix. Toggle the setting, send customers an email, done.
Stores with Deep Liquid Theme Customizations
All Liquid-based account templates stop working. You need app-based replacements through Customer Account UI Extensions.
Shopify Plus Merchants Using Multipass or SSO
Multipass is Shopify's tool that lets customers sign into your store using credentials from another system. It's not supported on new accounts. The replacement is a modern identity provider like Auth0 or Okta.
Stores with Custom Registration Forms
The new system doesn't support custom registration fields natively. If you collected extra info during signup (company name, tax ID), you need a third-party app like Customer Accounts Pro.
Headless / Hydrogen Stores
You'll need to migrate from deprecated Storefront API customer mutations to the new Customer Account API. Plan for API-level development work.
Common Migration Pitfalls (And How to Dodge Them)
Based on dozens of migrations across the Shopify ecosystem, here are the mistakes that trip up merchants most:
- Underestimating Liquid dependencies: Many stores have more customizations than they realize. Audit every file in your theme's customers/ directory. Custom CSS, JavaScript hooks on login forms, third-party scripts on registration pages, all need replacement plans.
- Forgetting about Flow automations: Workflows triggered by customer account events may behave differently with new accounts. Test them.
- Not communicating the change: The #1 avoidable problem. Customers who don't know about the switch will try their old password, fail, and either contact support or abandon your store. A simple email prevents 90% of confusion.
- Skipping the test window: Use those 30 days. Watch login rates, support tickets, and conversion. If something's off, you can still revert.
- B2B shared email challenges: Companies using one shared email (like mailto:[email protected]) face friction with OTP login. Plan for individual buyer accounts or an identity provider with role-based access.
Step-by-Step Migration Playbook
Step 1: Audit Your Current Setup
Go to Online Store → Themes → Edit Code. Review everything in the customers/ directory. Note every customization. Check: Multipass? Flow automations tied to account events? Third-party apps on account pages?
Step 2: Map Customizations to Replacements
- Custom login styling → No-code accounts editor
- Custom registration fields → Customer Accounts Pro app
- Loyalty on account page → Loyalty app's account extension
- Wishlist display → Wishlist app's account extension
- Multipass/SSO → Identity provider (Auth0, Okta)
Step 3: Install Replacement Apps
Search the Shopify App Store for "customer account extensions." 800+ available. Install and configure before switching.
Step 4: Switch to New Customer Accounts
Settings → Customer accounts → Select new option. The 30-day revert window starts. All customer data carries over automatically.
Step 5: Communicate the Change
Send an email: "We've upgraded your account for better security. You'll now sign in with a code sent to your email." Update your help center too.
Step 6: Monitor Key Metrics (2–4 weeks)
- Login success rate: Are customers completing the new flow?
- Support ticket volume: Any spike in "I can't log in" tickets?
- Checkout conversion: Any dip correlating with the switch?
- Password reset requests: Should drop significantly, track it as a win.

What Happens to Customer Data During Migration?
Your data is safe. All customer accounts, order history, saved addresses carry over automatically. Customers don't re-register. The only change they experience is the login method, code instead of password.
What doesn't transfer: Liquid customizations on account pages, Flow automations tied to legacy triggers (re-test these), Multipass configurations, and custom CSS/JS targeting legacy account page classes.
Post-Migration: KPIs to Track
- Password reset rate: Should drop dramatically. Pre-migration, this is the #1 support ticket. Post-migration, it should nearly disappear.
- Account creation rate: With no registration form, more customers should create accounts. Track weekly.
- Returning customer conversion: Passwordless login reduces friction. Studies show passwordless flows can improve conversion by 20%+ and reduce drop-offs by 35%.
- Support ticket composition: "Password" and "login" tickets should decline. If "code not received" spikes, check email deliverability.
- Account page load time: New extension-based pages typically load faster than legacy Liquid pages.
Quick Migration Checklist
Before You Switch:
- Audited all files in customers/ theme directory
- Listed every Liquid customization needing replacement
- Checked for Multipass/SSO usage
- Reviewed Flow automations tied to customer events
- Installed replacement apps/extensions
- Prepared customer communication email
- Set up tracking for key metrics
After You Switch:
- Tested login flow on mobile and desktop
- Verified customer data carried over
- Confirmed replacement apps working on account pages
- Sent customer notification email
- Monitored support tickets daily for first week
- Checked metrics at 7, 14, and 30 days
- Made go/revert decision before 30-day window closes
Final Thoughts
Shopify deprecated legacy customer accounts for a reason. The old system was holding merchants back, password resets clogging support queues, fragile templates breaking on updates, no access to modern features.
The new system is better. Passwordless login, native B2B support, 800+ app extensions, self-serve returns, store credit, these are what customers expect in 2026.
Migrate now and get the 30-day safety net, time to test, and the luxury of communicating changes on your own terms. Wait, and you get a forced cutover with no support.

Frequently Asked Questions
Q. What does "deprecated" mean for my store?
Shopify stopped developing and supporting legacy accounts. Your setup still works, but you're on unsupported infrastructure. The final sunset is coming later in 2026.
Q. When is the final sunset date?
Not announced yet. Confirmed for later in 2026. Don't wait, migrate now while you have the 30-day revert window.
Q. Will customers lose their accounts?
No. All data transfers automatically. Customers don't re-register.
Q. Do customers need new passwords?
No, because the new system doesn't use passwords. Customers sign in with a one-time 6-digit code sent to their email. They can also use Shop App credentials, passkeys, or social login.
Q. What happens to Liquid customizations?
They stop working. Replace with Customer Account UI Extensions or the no-code editor.
Q. What is Multipass, and does this affect it?
Multipass lets you sign customers using credentials from another system. It's not supported on new accounts. Replace with Auth0, Okta, or a similar identity provider.
Q. Can I revert after switching?
Yes, within 30 days. After that, it's permanent.
Q. Do I need a developer?
Simple stores: no, it's a toggle. Heavy customizations, Multipass, or custom forms: yes.
Q. How long does migration take?
If the website is simple, migration can typically be completed in under an hour. However, if there are customizations or complex features, the migration process may take longer, ranging from 1–2 weeks for moderate cases, to 3–6 weeks including testing for more complex setups.
Q. Is there a cost?
The system is free. The cost is development time for rebuilding custom functionality. Cheaper than a broken login when the deadline hits.
