[Important] This feature was removed in the update on September 10, 2026. The re-authentication feature that ran when a customer logged back in via Shop Pay no longer operates. Please see the details below.
Summary of the removal
Delete Me's "Shop Pay re-authentication feature" was removed in the update on September 10, 2026 (v1.2.3).
As a result, the following tags that were previously applied on re-authentication will no longer be applied:
shop_pay_reactivatedshop_pay_reactivated_on:YYYY-MM-DD
Note: The "Login with Shop" and "Shop" tags applied to customers are added automatically by Shopify and are unrelated to this feature or this change (they will continue to be applied as before).
Why it was removed
We confirmed that when a customer who has withdrawn (logical deletion) logs back in with the same Shop Pay account, Shopify automatically creates a new customer ID (a new customer record).
Because of this, the returning customer is treated as a separate customer from the previous record, and their activity is never linked to their past purchase history. In other words, the goal of "a deleted customer not being linked to their past history" is already achieved by Shopify's own behavior, even without the re-authentication feature.
For these reasons, we determined the feature was no longer necessary and removed it. Please note that the withdrawal / logical deletion (masking) behavior itself is unaffected.
Frequently asked questions
Q. What happens to the shop_pay_reactivated tags that were applied before? A. They will no longer be newly applied. Tags applied in the past are not removed automatically, so if you no longer need them, please delete them manually from the admin.
Q. If a customer who has withdrawn makes another purchase via Shop Pay, will it be linked to their past orders? A. No. Because Shopify creates a new customer ID at re-login, the new order is linked to the new customer.
(For reference / archive) Specification of the "Shop Pay re-authentication feature" before removal
The following describes how the feature worked before it was removed on September 10, 2026. It is kept here for reference and record-keeping.
A new feature has been implemented to detect Shop Pay users who previously deleted their accounts using the Delete Me button. When such a user logs back into the store via their Shop Pay account, "Delete Me" will automatically detect them. This feature helps prevent accidental purchases by returning users.
Shopify Customer Data Upon Re-login
When "Delete Me" detects a re-login from a previously deleted Shop Pay user, the following updates are applied to their Shopify customer profile:
Tags
The following tags will be automatically added to the customer profile:
shop_pay_reactivatedshop_pay_reactivated_on:20XX-XX-XX(The specific date of re-login)
Email Address
The email address will be automatically restored from its masked version to the original email address.
Name
The name will remain masked.
To update the name, use one of the following methods:
Admin Manual Update: Store administrators can change the name via Shopify Admin > Customers.
Customer Self-Update: Customers can change their names directly through the storefront. You can also install an App Block to prompt users to update their information upon re-login.
Installing App Blocks to Prompt Information Updates
When a previously deleted Shop Pay user logs back into the store, you can display an App Block on the storefront to encourage them to update their personal information.
Function: This block automatically appears to reactivated users, prompting them to correct their "Masked Name" or other profile details.
Setup: You can configure and position this element using the Shopify Theme Editor to ensure a seamless re-boarding experience for the customer.
