In addition to providing users with a variety of new features in the upcoming Windows 8 platform, Microsoft is also keen on ensuring that their data remains safe and that there are various ways in which they can protect their personal information.
One of these is picture password, a feature that should offer users a better experience when it comes to signing into their computers, while adding an extra level of security.
The feature is available only for devices that feature touchscreens and consists of performing specific gestures on a photo to unlock the computer.
Of course, users can continue using long passwords or PINs to lock their devices, but having gestures on a picture set as the security measure on a device can prove an easier and also funnier way to deal with keeping files on a device private.
