iOS 11.3 won't be the biggest system update, but Apple will still add a lot of new features. In the first beta iOS 11.3, evidence was found that Apple is working on a new way to authenticate on the network.
The function will allow owners of iPhone and iPad to register on any sites through their Apple ID. In addition, a special QR code can be scanned with a smartphone camera, and a page with registration via Apple ID will open. Thus, you provide the site with the following personal information: your name, e-mail and other minor details.
Google and Facebook already have a service with which users can register on sites through their accounts Google or Facebook, which is significant saves time. Apple will do something similar, but with some unique features and additions for sure.
It is not yet known if the new feature will debut in iOS 11.3, which will be released this spring, or if we still have to wait for the release of iOS 12.
