How does “Sign in with Apple ID” work?
“Sign in with Apple” is a security feature implemented by Apple a year ago. Now, if your app offers another third-party sign-on system, Apple requires it to add the above-mentioned button. Aside from this requirement, the “Sign in with Apple” could be added anywhere you offer the app.
By authorizing the Apple app ID end-users can choose whether or not to share their email with developers. If not, Apple generates a random email address that will forward all emails from this address to the real one.
