What’s new in Shopify

If your store uses a connected OpenID Connect (OIDC) identity provider for customer accounts (such as Okta, Auth0, Microsoft Entra ID), you can now unlink a customer from your identity provider directly in the Shopify admin.

When a customer's account is linked to the wrong subject in your identity provider, the customer might see the following error when they try to sign in:

"The sign-in method you used doesn't match this account."

Previously, fixing this required contacting Shopify Support. Now you
can resolve it yourself.

To unlink a customer:
1. From your Shopify admin, go to Customers.
2. Click the customer that you want to unlink.
3. In the customer details section, click Unlink next to your identity provider's ID, such as Okta ID or Auth0 ID.
4. Review the subject ID displayed in the confirmation dialog and compare it with the subject ID for this customer in your identity provider, if you have access to that information. If the subject IDs do not match, unlinking the customer should resolve the The sign-in method you used doesn't match this account. error.
5. Click Unlink to confirm.

After you unlink, the customer is signed out. They can sign back in with their existing credentials, and a new link is created on their next sign-in. The customer's orders, and other store data aren't affected.

This feature is available to stores on the Shopify Plus plan that have connected their own identity provider to customer accounts.
