Do customers need new passwords after a Shopify migration?

On almost every migration call, someone asks what happens to customer logins. It's a fair worry. Regular buyers are often the most valuable people on the store, and nobody wants them locked out on launch day.

The short answer is that passwords don't move to Shopify, and on a new Shopify store they don't need to. Shopify's current customer accounts are passwordless. Customers enter their email, receive a one-time six-digit code and sign in. If their profile was imported, their history is waiting for them.

Why can't customer passwords move to Shopify?

Shopify's guide to importing customers is clear. You can't migrate customer passwords from another online store using a CSV.

That's a sensible security choice. Other platforms store passwords in their own protected formats. Moving them between systems isn't something Shopify supports, whichever platform you're leaving.

So the question stops being how to move passwords. It becomes how returning customers get back into their accounts with as little effort as possible.

How do customers sign in after the move?

Shopify's customer accounts use passwordless sign-in. A customer enters their email address and receives a one-time six-digit code. A password isn't required.

Shopify also offers other routes in.

• Sign in with Shop, for customers who use Shop Pay.
• Social sign-in with Google and Facebook accounts.
• A new profile created automatically when an unknown email signs in.

Imported customers are covered too. Shopify says anyone with an existing profile can sign in with that email address. They'll see their orders and account information.

That changes the job. On older setups, a migration meant sending every customer an invite to set a new password. With passwordless accounts, the email address does the work. Our note on Shopify deprecating legacy customer accounts explains why the newer version is now the default for new stores.

What customer data should you migrate?

Passwords are the one gap. Most of what customers actually care about can come across. On our migrations we usually move these.

• Customer profiles, with names, email addresses and phone numbers.
• Saved addresses, so checkout doesn't start from scratch.
• Order history, linked to the right customer.
• Tags and notes your team relies on.
• Email and SMS marketing consent, carried across accurately.

Consent deserves care. Shopify's customer CSV has yes or no fields for email and SMS marketing. Shopify also reminds merchants to only send marketing emails to customers who have opted in. Map consent from the old platform exactly as it was given.

The email address is the thread that ties it all together. If a customer's email is wrong or duplicated in the old system, their history won't match the address they sign in with. We clean duplicates and check email formats before the import, not after.

What does a smooth account handover look like?

We treat customer accounts as part of the cutover plan. Regular buyers should sign in, find a past order and reorder on day one.

1. Audit the old accounts. Count active customers, find duplicates and note anyone who signs in often.
2. List what the account area does today. Past orders, saved addresses, wishlists, loyalty points, subscriptions or reorder lists.
3. Map each feature to Shopify. Some are native. Some need an app. A few need a custom build.
4. Import and check. Sign in as a sample of real customer profiles on staging and confirm their orders and addresses.
5. Tell customers before launch. A short service message explains the new code-based sign-in and that their history is still there.
6. Add help at the login page. One line about the six-digit code saves a lot of support emails.
7. Watch the first week. Track sign-ins, support tickets and reorders, then fix anything odd quickly.

The timing of step five matters. Send it close to launch, so customers remember it when they next visit.

What about trade and wholesale customers?

B2B buyers need more care. They often sign in weekly, reorder from memory and expect their own prices on screen. If the login trips them up, they pick up the phone.

On Shopify, trade buyers sit inside company accounts, with catalogues that set what each company sees and pays. The migration has to rebuild those relationships, not just the individual customer records. Each buyer's email needs to link to the right company and location.

We did this on Fáilte Foods, moving companies, customers and products from Magento to Shopify Plus with a Business Central integration. Our B2B commerce service covers how company accounts and trade pricing fit together.

How do you avoid a spike in support emails?

Most login problems after a migration come from surprise, not from the technology. A customer expects a password box and sees a code request instead.

A few small steps prevent that.

• Update help pages and FAQs that still talk about resetting a password.
• Brief your customer service team on the new sign-in before launch day.
• Check that the sign-in emails come from your domain and look like your brand.
• Test the full journey on mobile, since most code emails get opened on a phone.

The same thinking applies to search traffic. Our guide to keeping your Google rankings in a Shopify migration covers the redirect side of a calm launch.

Where parallel helps

We run Shopify migrations from Magento, WooCommerce, Wix, BigCommerce, Salesforce Commerce Cloud and custom builds. Customer data, order history and the sign-in journey are planned with the rest of the move. They're never left to launch week.
