Since the Windows 8 Consumer Preview came out i've been using this version on my corporate laptop.
As far as I have tested, it works just great! No issues at all!
One of the new things I noticed was the picture password.
These are a set of gestures in relation to points on the image that you would repeat to sign in.
These gestures will take into account the shape, the start and end points, as well as the directionality. However, the shapes and gestures are limited to tapping and tracing a line or circle. Microsoft found that limiting the gestures improved the speed of sign-ins by three times compared to allowing freeform methods.
This feature is mainly used for tablets, but can also be used on laptops.
Instead of a finger, the mouse cursor can be used.
Microsoft claims it is a safe replacement for a password, but the gestures can be easely remembered by colleagues standing next to you, so I have some doubts this will actually be used on other devices than tablets.
So, how can this feature be enabled?
In the user settings you are able to choose "Create a picture password" under Sign-in Options.
In my case I used a demo image for cloud based routing :).
In the left column you can choose to use the selected picture or choose another.
When making the gestures an arrow is shown in the screen ( not the black ones on the image but a light grey one ).
I just followed the arrow on the picture.
To confirm the password, you need to make the gestures again in the same order.
Click finish to make your picture password final.
To gain access to your machine you need to make the gestures you entered during the wizard.
Cool feature for tablets but I think it's not a replacement for a corporate password.
But it's cool to play with :).
