There are three ways by which you can login using your local user account. First is the old password method, second is to use a picture pattern and third is to use a 4 digit pin (like in a phone). You can get to the option via control panel.
First one, password method is self explanatory. Second method, to use a picture pattern is mostly aimed at tablets and desktops with a touch screen. You need to select a picture and a gesture to create a password which will be uniquely yours.
Third one is to use a 4 digit pin, like in a mobile phone.
