A Shopify Plus user is considering switching from “new customer accounts” to “classic customer accounts” to enable Multipass compatibility, which only works with the classic version.
Key concern: How will existing customers (who don’t have passwords under the new system) be affected by the switch?
Testing results: One user confirmed the switch is safe—existing customers are prompted to create a password when logging in, and they retain access to all previous orders. The experience may feel unusual for customers who already had accounts, but functionality is preserved.
Important consideration: Future Shopify features (like Store Credit) will likely require new customer accounts. An alternative solution is Shopify’s SSO framework for identity providers, which supports new customer accounts without needing Multipass. Apps like Customer Accounts Pro can add customization to new account profile pages using customer metafields.
Status: The discussion provides a tested workaround but highlights a trade-off between current Multipass needs and future feature compatibility.

We are using Shopify Plus and have been considering switching from “new customer account” to “classic customer account” because multipass is only compatible with the latter.
Could you please explain the impact on existing users created under the new customer account if we switch to the classic customer account?
Customers with the new customer account do not have passwords, so do I need to issue temporary passwords and notify existing customers when switching, or is it possible to leave a login method for new customer accounts on Shopify and prompt them to register passwords when logging in?
I couldn’t find the answer in Shopify Help, so I would appreciate it if someone could explain.
So I tried and it is safe to do so. Switching from New to Classic customer account will ask customers to create an account when login. It is a bit weird for customer who already had an account on the new version, but when done they’ll have access to all they previous orders.
Hi there, moving forward, a lot of the new features Shopify is rolling out (such as Store Credit) will probably require New Customer Accounts. If you’re currently using multipass but want to consider new Customer Accounts, you can check out Shopify’s latest single sign-on (SSO) framework: https://help.shopify.com/en/manual/customers/customer-accounts/new-customer-accounts/identity-provider. This should be supported by the latest Customer Accounts model.
If you’re looking for more customization on your New Customer Account profile page, you could also check out an app like Customer Accounts Pro. With it, you can create profile form fields where customers can input or update their profile data themselves on the profile page. All the profile fields are created as Shopify customer metafields.
