Connect with shopify app

I develop a new Shopify app and I would like to embed my dashboard into the Shopify admin.
Currently, my dashboard has Auth0 authentication and I would like the users (admins) to have a silent authentication while I open the dashboard in the Shopify store admin panel.
How can I enable multiple stores authentication?
How can I make the authentication at the backend with the Shopify user token?
Thanks,
Arik

Hello. Welcome to our community!

We recommend to contact Shopify as this seems to be related with their ability to support external IdPs.

Thanks.

Heads up, team!

The new Shopify Customer Accounts experience now supports external IdPs via OIDC, allowing you to integrate Auth0 for MFA, passwordless login, SSO, and attack protection, while maintaining a familiar “Sign in with Shop” option for your customers. Check the details in our blog post
