Make signing in easy.
Provide a fast, secure, and privacy-friendly way for users to set up an account and start using your apps and websites.
Planning
Sign in with Apple allows you to set up a user account in your system, complete with name, verified email address, and unique stable identifiers that allow the user to sign in to your app with their Apple ID. It works on iOS, macOS, tvOS, and watchOS. You can also add Sign in with Apple to your website or versions of your app running on other platforms. Once a user sets up their account, they can sign in anywhere you deploy your app.
Examples of Use Cases
With Sign in with Apple, it’s easy to:
- Allow users to create an account early in your app experience if your app has limited functionality without an account.
- Allow users to create an account after interacting with features of your app. For example, to save progress or set up a profile.
- Allow users to create an account after completing a purchase as a guest.
- Allow users with existing accounts to sign in or reauthenticate to any version of your app or website.
Guidelines
Apps that use a third-party or social login service to set up or authenticate the user’s primary account with the app must also offer Sign in with Apple as an equivalent option. As you plan and design your app or website for Sign in with Apple, make sure to follow these guidelines. In addition, the Human Interface Guidelines include downloadable left-aligned, center-aligned, and logo-only buttons. App updates must follow these guidelines starting June 30, 2020.

Email Relay Service
Apple’s private email relay service is used by privacy-conscious users that keep their personal email address private when setting up an account. In order to send email messages through the relay service to these users, you will need to register your outbound email domains, subdomains, or email addresses. The registration process provides informational Sender Policy Framework record checks and does not require website server file verification. Organizations can register up to 100 outbound email sources. Individuals can register up to 32.
If we detect that emails sent from your account were unable to be delivered by Apple’s private email relay service, we’ll send periodic email notifications to Account Holders and admins. Account Holders and admins can turn off these email notifications in the More section of Certificates, Identifiers & Profiles.
