Out of the box your mobile app natively uses Shopify Authentication, specifically Classic Customer accounts, to authenticate users. If you have your own authentication endpoint you would prefer to be the source for your app you can do so via Shopify Multipass (more information from Shopify here)
Leveraging Shopify Multipass and your Auth endpoint allows the mobile app to both
- Sign in known customers using email and password
- Create new customers using email and password
- Support Forgot Password updates through your preferred path
The following page details the expected API inputs and outputs to help authenticate your shoppers.
