Shopify Auto Login (SSO) to Access External Apps & Multiple Stores

SSO Integration

Can I integrate Shopify's login system to authenticate users for my custom app?

Yes. Our application supports standard authentication protocols such as SAML, OAuth/OIDC, and JWT, allowing you to connect custom-built applications and enable login using Shopify customer accounts as the authentication source.

Can I share customer data or tags between Shopify stores when they log in?

Yes. When a user logs in via Single Sign-On using Shopify as the Identity Provider, customer attributes, tags, and metafields from the IDP store are passed securely to the connected Shopify stores at login. This ensures consistent user identity and access control across stores, without requiring users to create or manage separate accounts for each storefront.

Can I use Shopify’s customer accounts directly as an auth system for any external tool?

Yes. By using Shopify as the Identity Provider (IDP), you can set up Shopify Customer Accounts to act as the primary authentication layer for external platforms such as LMS, CRMs, communities, mobile apps, and other Shopify stores, enabling Single Sign-On without separate user credentials.
