Apple's Single Sign-On feature on Apple TVs is similar to the Apple ID single-sign-on found in the iOS 11.3 beta, which allows users to seamlessly log in to a different, different phone after logging invideoRoad, while the latter can mean just need to enter the Apple ID, the use of Apple's first-party certification can be seamlessly landed in iOS multiple sites or third-party platform, no longer need to use other accounts (such as QQ), without having to register an account .
In addition, there is a component in iOS 11.3 beta that lets users scan QR code, prompting users to Apple ID authentication when scanning with the camera application. It's unclear the true purpose of the system, but it is likely to be another convenient feature for Apple ID users, scanning code on a PC or Mac end website / platform.
If this feature can be achieved in iOS 11.3, then undoubtedly provide more convenience for Apple users, but also shows that Apple has decided to step up iCloudcloud serviceFeatures.
In previous iOS 11.3 Developer Preview summaries, we also saw iCloud iMessages. This feature was first available in iOS 11 and the first developer preview of macOS High Sierra, but was later removed from the public beta and is now back in iOS 11.3. After iCloud messages are enabled, your iMessage messages will remain intact on iCloud, turning all devices on and you will see the full iMessage history.
Earlier in the preview, Apple showed new changes that iOS 11.3 will bring, including a new AR experience and ARKit 1.5 development tools, new emoticons,iPhoneBattery energy-efficient switch, new health functions and more. This big update will come in the spring.
