Sign In With Apple…Should You Use It?
Apple recently reported that its new “Sign in with Apple” feature will be part of the iOS 13 release in the fall of 2019. It promises to protect your privacy, and authentication experts say it could have an enormous impact on data privacy.
What Is Sign In With Apple?
With Sign In With Apple, you’ll be able to log into your applications. It offers a single-sign-on functionality, much like other sign-in buttons such as Facebook’s, Google’s and Twitter’s.
What Are The Benefits Of Using Apple’s Sign In?
When you sign onto apps, Apple will mask your personal information and email address. But the application will still be able to contact you.
Unlike with Google, Facebook and Twitter, your email won’t be passed on to the developer. You can opt not to allow this, but you won’t be able to use their sign-in service. If you do choose to let Google, Facebook or Twitter track your email, they will also be able to see the applications you use.
Aaron Peck from Oauth explains:
“The way most “sign in with [blank]” systems work is that the app you’re signing in to will get your username on that service and likely also your email address,” he explained. “These apps can sell your email address to advertisers, or correlate your activity between unrelated applications by matching your username.”
Apple solved this problem with its single-use anonymous email address. You’ll be able to share the information you choose with the application. Apple creates a random, anonymous, single-use email address for each application. Apple then forwards emails sent to that address on to you. You have the option of deactivating the single-use email address whenever you want.
By using Sign in with Apple and the single-use email address, your true email address won’t be tracked. Apple is offering this to provide a more private option for use. And they are offering developers a way to provide a fast one-step login without forwarding their user’s data to another company. Apple’s button will also work on websites.
Can You Use Apple’s Sign In With Any Application?
No… only applications that integrate their systems with Apple’s Sign In button. Some may opt not to because they won’t be about to use your information for marketing purposes.

These are the devices that will be able to use iOS 13:
Is There Anything Else To Consider When Using Sign in with Apple?
If you are a developer, there may be. There are some concerns surrounding Apple’s terms and conditions for application developers. If they offer Google, Facebook or Twitter’s sign in, they must also offer Sign in with Apple.
And there’s more. According to Reuters:
Apple will expect developers to place their login button above Google’s or Facebook’s.
Apple Inc will ask developers to position a new “Sign on with Apple” button in iPhone and iPad apps above rival buttons from Alphabet Inc’s Google and Facebook Inc, according to design guidelines released this week.
The move to give Apple prime placement is significant because users often select the default or top option on apps […]
Apple’s suggestion to developers to place its login button above rival buttons is part of its “Human Interface Guidelines,” which are not formal requirements to pass App Store review. But many developers believe that following them is the surest way to gain approval.
This means that some app developers won’t have an incentive to actually add the Sign in with Apple feature. But Apple is getting around this by mandating that if developers what to place their app in the Apple App Store, and they already offer a third-party sign in, they must offer Apple’s.
Apple’s terms and conditions don’t require this for applications with a dedicated login system, and those that don’t use third-party buttons from Google or Facebook.
What’s The Benefit For Apple?
Sign in with Apple will improve users’ privacy and provide a far better experience than others.
Will LaSala, director of security services and security evangelist at OneSpan, tells us more:
Apple is going one step further than traditional single sign-on, they are forcing their users to use stronger authentication, such as Apple’s FaceID and TouchID,” he said, noting that Sign in with Apple will ask mobile app users to use the biometrics functions.
The use of adaptive authentication is what should be celebrated – the ability to prevent login tracking or protect a user’s information is a secondary benefit. Any way that we can get users to move to adaptive authentication that is easy and portable across many sites and platforms is a security win for the internet.
Apple is positioning themselves as the privacy provider. So when we want more privacy, Apple hopes we’ll choose to use their technology. It’s a great marketing strategy…something that Apple excels at. We think many people will want to use Sign in with Apple due to its privacy features.
