Your use case can be achieved using our miniOrange Single Sign-On application for Shopify.
Using our application you can allow users and staff members to single sign-on into, storefront, e-commerce web applications, Shopify admin, and new customer accounts or B2B accounts using their Microsoft Entra ID credentials. We also provide SSO on both Plus and Non-Plus stores.
You can follow this step-by-step guide to configure Shopify SSO using Microsoft Entra ID as an identity provider (IDP).
