With the new service, Apple wants to enable a convenient login alternative.
With its own service Apple wants to simplify logging into apps and websites. Now, instead of having to create a new account for every app or website, users can instead tap on “Sign in with Apple” and receive immediate access, after authentication by Face ID or Touch ID.
Apps have the ability to ask for user’s name and email address, which they can choose to reveal or not.
If you want to keep the mail address for yourself, Apple provides as an alternative, an automatically generated disposable mail address, as Apple’s software chief Craig Federighi explained. It forwards messages to the real Apple ID address known only to Apple. For each new app, a separate disposable address is created, so that the user can turn off this communication channel for unwanted messages at any time.
Apple’s Login Service Without Data Collection
At the same time, Apple promises not to collect any data when using the service. “Sign in with Apple” should in particular could be a alternative to the login services of Facebook and Google. Facebook and Google receive valuable data about the app usage behavior of their users via their login services and even pass on certain information to the respective app provider.
In order to achieve a quick and widespread use of “Sign in with Apple”, Apple makes the service obligationary for all apps that already offer a third-party login service, such as Facebook. The service is presumed to be “an option for apps that already support third party sign in services”. According to a statement from Apple changes to app store rules will be made.
“Sign in with Apple” does not only work in the Apple ecosystem, developers and app providers can integrate the service in their apps on other platforms such as Android, Windows or Web. The login service will be introduced in the fall with iOS 13.
