Question about "Sign in with Apple".

Can 2 apps from 2 different developer accounts (hence, 2 different team ID) share authentications?

In other words, can I get consistent user ID from 2 different app under 2 different developer account? Is there a way to configure that from developer portal?

Thanks Bill

Hi @bill-sched,

Can 2 apps from 2 different developer accounts (hence, 2 different team ID) share authentications?

No. For Sign in with Apple, all user information provided by Apple—the user ID and private relay email address—are team-scoped. Team A will receive one value for each, and Team B will receive another value for each. These values should be treated as private metadata and should not be shared or mapped across teams.

If you'd like to associate these users, consider transferring the app to either team and performing a user migration. See the following resources for more information on that process:
