How Will You Use Sign in With Apple?
Instead of using a social account or using email as verification, says Apple, your Apple ID sign-in will create a unique random ID. If the app or website asks for your email, you’ll be able to either share your real one or hide it behind a randomly generated one.
According to CNN, when using a compatible app, you’ll first verify using Face ID or Touch ID on your iPhone (and go through two-factor authentication if your Apple ID has that enabled), then you’ll see an option to tap a Sign In with Apple button or enter your email address as usual. This makes sure that your login info is secure and private while also making sure you can’t be tracked online from your social logins via Facebook or Google. While Apple only showed this working on an iPhone, you’ll likely be able to do the same thing from your Apple Watch, iPad, and Mac.
This gets a little technical, but TechCrunch says that non-Apple apps might be able to use a web-based workaround to include Sign In with Apple, too with JavaScript, called Sign In with Apple JS. In addition, if you already have an account for and app or website via an email address (and it’s stored in iCloud), Apple will alert you and offer you the option to use that older account’s sign-in info.
Ultimately, if privacy is important to you and you’re an Apple user (even if you just use iTunes/Apple Music to purchase your songs or TV shows), you should be well served by Sign In With Apple. Now you’ll be able to use apps and sign in to websites without worrying about being tracked or having your personal information used without your knowledge.
According to Apple
As Apple says on its Developer website:
“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.”
Announced at WWDC in June of 2019, Sign In with Apple is a part of iOS 13 and will work with your iPad, Apple Watch, and Mac computers. In addition, Apple says that it can be implemented easily via web technologies, which means it will probably show up on other devices (think Android apps and PCs) in the future as well.
