At WWDC 2019, Apple introduced attendees and viewers the new “Sign in with Apple” feature available on all devices. While this feature isn’t necessarily groundbreaking or the go-to go-to take on a MacBook or iPhone, it has since become a cherished part of Apple’s suite of device features.

Both Apple Pay and “Sign in with Apple” are two ways Apple continues to push for a simpler and more intuitive experience not only from a hardware and operating system perspective, but now also in third-party applications.

What is “Sign in with Apple”?
In recent years, registration forms on the web have been simplified in many different ways. One of the most common ways to simplify the process is by using OAuth, an open protocol that enables secure authorization on web, mobile, and desktop applications.
You have probably been on websites where you have been given the option to sign up with an email address or by linking a popular service account such as Google or Facebook. In most cases, this is OAuth in action.

Apple’s “Sign in with Apple” feature works in a very similar way to OAuth. If you’ve seen the Apple Pay button on any website or mobile app, Apple’s new login button is very similar.
If your device is running iOS 13 or later, you can use your device’s Apple login information to create an account instantly and easily. The only requirement is that you have two-factor authentication enabled on your Apple ID.
“Sign in with Apple” offers some very interesting benefits that you won’t find while using OAuth and similar services. One example is Apple’s “Hide my email” feature.
