Since each shopping cart has its own password encryption peculiarities, so it is impossible to migrate customer passwords from another platform to Shopify. Moreover, Shopify is the hosted e-commerce solution that it is hard to touch to the Shopify database and check Shopify password encryption. As a result, only customer records are migrated to Shopify instead of customer accounts.
You can use the Bulk Account Inviter app to invite your customers to activate their accounts for your online store. This app is useful after you have imported customer accounts from another platform or from another Shopify store.
