It looks like Apple is about to embrace biometrics beyond the fingerprint.
The iPhone 8, Apple's newest device expected to be unveiled in September, could have a feature that means you can unlock your phone using just your face.
The tech was spotted by developers analysing the code for Homepod, which isn't expected to go on sale until December.
The addition of facial recognition technology to an Apple device would be a big boost for biometric technologies and the code hints at a full developer kit for biometrics, named BiometricKit, the same naming convention previously used for them. For example ARKit is its augmented reality developer toolkit, something announced at its developer conference earlier this year which is expected to propel the technology into the mainstream.
It has already had fingerprint recognition with Touch ID, first introduced in the iPhone 5s in 2013, while rival Samsung was eyeing a step forward with iris-canning tech in its doomed to failure Galaxy Note 7 (not because of that particular feature, though).
The leak also reveals a bezel-less screen - that is, a screen that stretches across the whole device rather than being "framed".
Expectations are high for Apple's newest device, dubbed the iPhone 8, which comes in the year the iPhone celebrates its 10th anniversary. The secretive tech firm could give a rare update on its progress tomorrow when it releases third quarter earnings as analysts speculate there may be a delay on the iPhone 8 hitting the market.
