- ID: MOB-6
- Level: Recommended
- Chapter: [Store review and listing](https://agentwranglers.se/playbook/mobile-apps/store-review-and-listing)
- Rule: An iOS app with a third-party login, such as Google, also offers a login that shares only name and email. That login lets people hide their email.
- Applies when: The project has user accounts.
- How: Sign in with Apple meets Apple's three conditions. Apps that use only your own accounts, and business or school apps that need an existing company account, are exempt. Link the new login to the right account as [link a provider login only to an account its owner controls](https://agentwranglers.se/playbook/accounts/sign-in-methods/link-provider-login) says. The choice of methods is in [let people sign in with an account they already have](https://agentwranglers.se/playbook/accounts/sign-in-methods/provider-sign-in). Hidden email addresses relay mail, so send from a domain you register with Apple.
- Check: On the iOS sign-in screen, every third-party login sits beside an option that meets guideline 4.8. A test sign-up with a hidden email receives the welcome email.
