Sign in with Apple: When It Is Required and How to Comply

The Requirement

If your app uses a third-party or social login service (including Google, Facebook, Twitter, or any OAuth provider) as its primary authentication mechanism, you must also offer Sign in with Apple. The Sign in with Apple button must be at least as prominent as other login options. This applies to all apps on the App Store, including iPad and Mac apps.

Exceptions

You do NOT need Sign in with Apple if: your app only uses email/password login (no third-party), your app uses a company-specific account system (e.g., employees logging into their company app), your app authenticates with a specific third-party service that the app depends on (e.g., a bank's app using the bank's login), or your app uses government or education identity systems.

Implementation Best Practices

Use Apple's official Sign in with Apple buttons and follow their Human Interface Guidelines for placement. Handle the relay email service gracefully (users can hide their real email). Store the stable user identifier Apple provides, not the email. Implement silent token refresh for returning users. Test with multiple Apple ID configurations including those with hidden email addresses.
