I’ve reviewed the Shopify Multipass documentation and understand how it allows logging a user from an external website into a Shopify store.
My use case is the opposite: our databases are already synced via webhooks, and I want users who log in to their Shopify customer account to be automatically logged in to our external website as well.
Can Shopify Multipass be used in this direction, or is there a recommended approach for achieving single sign-on from Shopify to an external system?
Is there any alternatives other than multipass?
