Microsoft uses images as passwords for Windows 8

Microsoft revealed that one of the latest improvements in Windows 8 is the "Picture password" feature, which uses images to secure computers.

This feature is designed for touch screens, especially for tablets. According to Microsoft, this is an optional function next to the standard password with regular characters.

This security application works based on the user's three-finger movement done on the photo. Users can draw lines, create dots or draw curves instead of entering security characters to unlock.
