How good will Apple's Face ID be? Will it be able to tell twins apart?

Apple is expected to roll out facial recognition on the newest high-end iPhone, likely called iPhone X, on Tuesday. Will it be good enough to tell twins apart?
Face ID will be a first for Apple. And Apple has to get the technology right the first time if it’s used for Apple Pay, as reports are indicating, which requires “enterprise-grade” authentication.
Experts say that the technology could prove extremely useful for consumers. “Just like Apple legitimized fingerprint biometrics when they introduced the capability, I believe they will be able to legitimize facial biometrics and authentication,” explained Jackson Shaw, senior director of product management at security specialist One Identity, in a statement emailed to Fox News. “In any situation where we rely on or require an authentication, the ability to prove that you are you simply by raising your iPhone to unlock it could be a time saver and a great way to reduce the risk associated with impersonation or hacking.”

However, one litmus test for the reliability of facial recognition is the ability to distinguish between identical twins, as shown with Microsoft's Windows Hello face ID technology now used widely on Windows 10 PCs.
Microsoft’s technology was largely successful, as reported by The Australian in 2015 when testing six pairs of identical twins. There was one instance where a pair of identical twins couldn’t log in but Windows Hello never erroneously granted access.
{{#rendered}} {{/rendered}}Windows 10 Hello uses, among other things, near infrared (IR) imaging to authenticate and unlock Windows on a PC. Hewlett-Packard’s EliteBook x360 laptop, for example, which is capable of unlocking Windows 10 with facial recognition, has an infrared camera and IR “emitters” that it uses during the facial recognition process.

The IR ability is important because it can provide a consistent image in diverse lighting conditions that also allows for subtle changes in appearance including facial hair, cosmetic makeup, in addition to identifying facial “landmark” points that correspond to eyes, nose, and mouth, and other facial features, according to Microsoft.

Another critical element of Windows 10 Hello authentication is 3D imaging, according to documentation on Dell’s website.

Will Apple raise the bar?
Apple is also expected to use infrared face detection on its new high-end iPhone X, according to recent reports.

So, based on those reports, Apple’s Face ID appears to be sophisticated enough to pass the identical twins test.
