One of the cool new features I recently discovered in the latest leak (now that it has finally been made available for my Z10) is a picture-based security code, called Picture Password. You choose from a variety of different pictures and you choose one digit. The “code” is the placement of that digit in an exact area of your choosing on the picture, as illustrated below. It definitely does take some time to get used to and get right. At first, I didn’t really see the point of this new option but then I realized what this has over numeric/alpha codes and patterns. The number grid can be moved around by dragging any part of the image. So someone could be staring right at your screen as you unlock it and still have no idea
what your code is.
