windows 8 picture password

I am here with a new update of windows 8. Windows 8 developer build  conference held at Anaheim, California. Microsoft is going to introduce a new feature in windows 8. In windows 8, a user can chose a picture password. This is really a cool feature where you can draw lines to make a picture password for you. Here you can chose a circle, triangle, a line touching your lips to nose anything that you wish in windows 8 picture. You can also set a traditional password that we are using windows. So a user can authenticate in windows 8 by the two ways, by typing a password and by picture password.

I think we don't want to face a situation where we had kept a difficult picture password and we are not able to login.
