Apple introduces ‘Sign in with Apple’ to help protect your privacy

Apple has a new way to stop third-party sites and services from getting your information when you sign up to an app.

All too often, developers give users the chance to sign in with one-click — using data fed in from Facebook, Google or Twitter.

“Now this can be convenient, but it also can come at the cost of your privacy, your personal information sometimes get shared behind the scenes and these logins can be used to track you,” said Apple software engineering chief Craig Federighi at its annual developer conference.

Apple thinks it can do one better by allowing developers to add a “Sign in with Apple” button instead.

What’s the difference? Apple says it can authenticate a user using Face ID on your iPhone without turning over any of your personal data to a third-party company.

Federighi said users can create a new account on an app using its own one-click button “without revealing any new personal information.”

He noted that when apps ask for names and email addresses — typically auto-populated from a one-click login from a social networking site — you can still provide them if they wish. But when you don’t want to provide your real email address to protect your privacy, Apple will auto-generate a random “relay” email address that hides your real email address.

“That’s good news because we get each a unique random address, and this means you can disable any one of them and anytime when you’re tired of hearing from that app,” said Federighi.

“It’s really great,” he said. Yes, it really is.
