Clarification on Apple Sign-In Integration Across Multiple Applications

Dear Apple Support Team,

I hope this message finds you well.

Our tech team is currently working on integrating the Apple Sign-In feature, and we have a specific query where we would appreciate your guidance.

Background Context: We have several applications across different brands and are aiming to implement a unified sign-up and sign-in experience. Currently, we are utilizing a shared website to enable single sign-in functionality across all these applications.

Our Query: If we embed the same website in all of these applications and implement the Apple Sign-In within this website—using a dedicated Service ID that is configured with the App Store name and icon—will users consistently see the Apple Sign-In pop-up with the Service ID’s name and icon, regardless of which base application (e.g., App A, App B, etc.) the website is accessed from?

We would like to ensure a seamless and consistent user experience and want to confirm that the branding within the Apple Sign-In prompt will reflect the Service ID’s configuration, rather than that of the hosting app.

Looking forward to your guidance on this matter.
