The something you can do authentication factor refers to actions you can take such as gestures on a touch screen. As an example, Microsoft Windows 10 supports picture passwords. Users first select a picture, and then they can add three gestures as their picture password. Gestures include tapping in specific places on the picture, drawing lines between items with a finger, or drawing a circle around an item such as someone's head. After registering the picture and their gestures, users repeat these gestures to log on again later.
