New Sign In with Apple feature to boost user security & privacy

As part of iOS 13, its latest operating system upgrade for iPhones and iPads, Apple has introduced a new feature called 'Sign In with Apple' which will prevent third party services from viewing email addresses and other personal information of device users.
The new feature will be similar to the "Sign in with Google" or "Sign in with Facebook" features we use every day to sign up to and log in to dozens of websites and apps every day, except for the fact that the new service will allow iOS device users to control what information about them third party services can view and process.
"Instead of using a social account or filling out forms, verifying email addresses or choosing passwords, customers can simply use their Apple ID to authenticate and Apple will protect users’ privacy by providing developers with a unique random ID," said Apple.
"Even in cases where developers choose to ask for a name and email address, users have the option to keep their email address private and share a unique random email address instead.

Sign In with Apple to keep users' email addresses private

"Sign In with Apple makes it easy for users to authenticate with Face ID or Touch ID and has two-factor authentication built in for an added layer of security. Apple does not use Sign In with Apple to profile users or their activity in apps," the company added.
Basically, the new feature will involve Apple creating a random email address which will be used to log in to third-party services and will be visible to third parties. Any information sent by third-party services to the random email address will be forwarded to the email address of the user, ensuring that a user will be able to avail third-party services without actually sharing their email addresses.
The launch of the 'Sign In with Apple' feature is another initiative from Apple to further secure the identity and privacy of iOS device users after the company introduced the pathbreaking Face ID technology with iPhone X in 2017.
When launching the technology, Apple said that Face ID used the TrueDepth camera system's infrared camera along with proximity and light sensors to detect and map out the face of an iPhone X user. The system also utilised specialised hardware and a flood illuminator to create 30,000 invisible dots which helped in mapping a user's unique facial features. Unless you have an evil twin, you have no reason to worry, said Apple.
While testing Face ID, Apple made sure the facial recognition feature, unlike its predecessors from other tech giants, didn't fall for well-lit photographs or other faces that had similar features. The company even tested the software against face masks that mimicked the unique features of a human face.
