For those unaware, the iPhone X bids goodbye to Home Button. The TouchID has been replaced by FaceID in the smartphone. This means that there's no fingerprint sensor in iPhone X. iPhone X uses facial recognition to unlock the device. Users can set up FaceID by letting their iPhone X make a detailed digital "map" of their face. Apple claims that FaceID is a lot easier and safer. According to the company, there's a one in a million chance of someone being able to 'hack' your phone. FaceID is said to run on 'neural engine' powered by the company's A11 Bionic processor.
