One feature that Apple introduced today that I personally loved was Apple Sign-in, this removes the need for users to sign into apps using Facebook or Google and even allows users to generate random email addresses for privacy.
Sign In with Apple was built from the ground up to give users peace of mind about their privacy. Data collection is limited to the user’s name and email address, and Apple’s private email relay lets users receive email even if they prefer to keep their address private. Apple will not track users as they interact with your app.
Sign In with Apple works natively on iOS, macOS, tvOS, and watchOS. And it works in any browser, which means you can deploy it on your website and in versions of your apps running on other platforms. Sign In with Apple is designed to give you confidence in your new users. It uses on-device machine learning and other information to provide a new privacy-friendly signal that helps you determine if a new user is a real person or an account you might want to take another look at.
Every account using Sign In with Apple is automatically protected with two-factor authentication. On Apple devices, users are persistently signed in and can re-authenticate anytime with Face ID or Touch ID.
To ensure successful implementation this will be a mandatory requirement for users in apps that support third-party sign-in when it is commercially available later this year under updated App Store Review Guidelines.
