Sign In with Apple allows you to sign in to apps and websites using your Apple ID. Apple is adding enhanced privacy options for users in its continued effort to differentiate itself from Google & FaceBook.
Instead of filling out forms, verifying email addresses, and choosing new passwords you can Sign In with Apple to set up an account on apps and websites. Sign in with Apple will be released in iOS 13, iPadOS, macOS Catalina, watchOS 6 & tvOS 13 this spring.
All accounts are protected with two-factor authentication for improved security and Apple states it will not track your activity in apps or websites when using Sign In with Apple.
Sign In looks similar to how you sign into an app or website with Google or Facebook, but Apple is taking a shot at Facebook and Google by adding superior privacy features.
Signing in with Facebook or Google might seem easier, but a lot of your personal information is attached to them like your name, your location, your birthday and more. This information might seem innocent at face value but it can be used as prime security question fodder for your bank account or other sensitive data.
When using Sign In with Apple you can choose not to share your email address with the app or website. If you decide not to share your real email, Apple will generate a random, but real and verified, email address for the app or website to use.
All the emails from that app or website will then route to that address. You can choose to disable the app email address at any time like if they start to get spammy or you loose interest.
Sign In with Apple also ships with features that benefit iOS app developers including built-in two-factor authentication support, anti-fraud detection and the ability to offer a one-touch logon.
