Microsoft has announced plans to add a new feature called Picture Password to Windows 8.

"The technique starts with you providing a picture," writes PCWorld's Joseph Fieber. "You can position the picture as you like, and are then prompted to make gestures on the picture that become your authentication signature."

"There are three gesture types you can use; a tap, a circle, and a line," Fieber writes. "In a demo video at the bottom of this Windows blog post, the demonstrator draws a picture around his father’s head, connects his sister’s noses with a line, and taps on his mother’s nose."

Go to "Windows 8: Log On With Taps, Circles, and Lines" to read the details.
