One of the biggest privacy features shown during WWDC’s keynote this week was Sign In With Apple.
Apple is offering this as a more secure alternative to other third party logins, such as Facebook. And apparently it’s going to be mandatory.
An update to the App Store review guidelines from June 3 states:
"Sign In with Apple will be available for beta testing this summer. It will be required as an option for users in apps that support third-party sign-in when it is commercially available later this year."
This means that any developer that creates an app available in the Apple ecosystem and offers third party logins will be required to include Sign In With Apple as an option.
Sign In With Apple will offer users a anonymous way to log into apps and websites with Face ID. It won’t attribute your metrics to any other info or data on your account.
It will also allow users to bypass the need to provide an email address through random generations.
Apple will create an individual fake email address for every different app or site you use Sign In With Apple for. It will then forward updates and correspondence to your actual email account.
Sign In With Apple with launch with iOS 13 later this year.
