A user's primary account is the account they establish with your app for the purposes of identifying themselves, signing in, and accessing your features and associated services. Aside from user convenience, the fast adoption can be attributed to the App Store guidelines, which requires developers to offer Sign in with Apple when their apps use any third-party or social login services to access the primary account.Īpps that use a third-party or social login service (such as Facebook Login, Google Sign-In, Sign in with Twitter, Sign In with LinkedIn, Login with Amazon, or WeChat Login) to set up or authenticate the user's primary account with the app must also offer Sign in with Apple as an equivalent option. Since then, more and more apps and websites have added support. Hide My EmailĪpple introduced Sign in with Apple in 2019 with the iOS 13, iPadOS 13, and macOS Catalina updates. However, it's easy to lose track of the accounts you use with Sign in with Apple, as well as any throwaway email addresses you used to hide your actual address. More importantly, it can hide your personal email address using auto-generated disposable email addresses.


The "Sign in with Apple" service lets you create accounts with third-party apps and websites more easily using your Apple ID.
