Increasingly, Apple is turning its privacy stance into highly visible parts of its products.

One major WWDC debutante, an iOS 13 and MacOS Catalina feature called “Sign in with Apple,” might be the company’s most tangible act of privacy protection yet. It’s not a productivity, communications, or entertainment app with data privacy is an added-on guarantee. Its whole purpose is to help users preserve their own privacy as they move around the web. In that sense, Sign in with Apple may be the very first privacy product from Apple.

This might be one of the best new features Apple announced today. I never sign in to apps or sites using my Facebook or Google logins but lots of people do, giving up user data in the process.
