Picture Password Sign-in — Windows® 8
Keep wondering how many new features the upcoming Windows 8 would bring along, while another one has just been revealed — the Picture Password. It is a feature that lets the users sign-in by drawing a gesture on a select picture. This is something that would instantly do away with the need to type cumbrous mix of alphanumeric characters or even the necessity to remember them. The feature also diminishes the possibility of a password-crackdown, a practice often exercised by the hackers. Moreover, as Windows 8 has been developed as a touch-optimized operating system, the picture password would be one great way to sign-in.
So, how does it work? The user has to select a picture from his personal photo-albums and tap on a particular portion, draw a line from one section to another, or just make a circle around any part. Any of these gestures can be used to highlight a part of the image or a person in it. It is noteworthy here that Windows would remember the way a gesture is drawn by the user. Hence, it is important to use a gesture you can easily recall. In fact, the feature works on the principle of dimensional-division of the picture into coordinates and grids. It means that the Windows 8 would take into account the start point and end point of the gesture, as well as the center coordinates in case of a circular gesture.
Picture password is an optional way to log on to Windows. Therefore, the users, who like to stick to familiar ways when it comes to passwords and account security, can always choose to switch to the old method.
