9to5Mac has recently found codes in the iOS 11.3 which indicates a single sign-in option will be available soon which will be linked to your iCloud account. This would mean that you will only need to remember your iCloud login and you will be able to sign in to websites that support this feature
It is still unsure on how the actual process might be carried out, but based on assumptions, you will have to give websites access to “personal iCloud data” that would act as your login details for the website. Other than that, there are also elements in the code which will use the camera app to scan for a QR code and ask for your Apple ID. There is no date given on when this feature will be ready for users, but we should also expect that this feature may never come to the official release of iOS 11.3.
Another feature expected to come with the new iOS 11.3 update is AirPlay 2 as it was meant to come out in the iOS 11.2 update. AirPlay 2 will come with a much-awaited feature which will allow you to stream to multiple Apple TVs and speakers directly from the iPhone.
