We touched upon passwords a bit ago, but it’s important that we mention one of Windows 8’s more novel approaches toward system security: The picture password. Click on the Settings menu on Windows 8’s Charms Bar, and then click on the “More PC Settings” link. Click on “Users,” and then select the option to create a picture password.
What’s a picture password? In short, you start by selecting an image – any image you want. On this image, you’ll draw a combination of gestures, which can include circles, straight lines, and taps. The theory is that you’ll draw associations in a picture – like a line connecting you head to your favorite pet’s – that only you would know about, thus preventing a random stranger from successfully logging into your system. You have to nail all three gestures, in the order they were created, for your system to authenticate you.
