Abstract
In some examples, a computing device may display a user interface (UI) to configure a multiple print unlock. The UI may determine a first plurality of prints placed on a touchscreen. Individual prints of the first plurality of prints may include a thumb print or a fingerprint. After the computing device has been inactive for a predetermined amount of time, the UI may lock the computing device. The UI may determine a second plurality of prints placed on a touchscreen and perform a comparison of the second plurality of prints to the first plurality of prints. If the UI determines that the second plurality of prints matches the first plurality of prints, then the UI may unlock the computing device. If the UI determines that the second plurality of prints does not match the first plurality of prints, then the computing device may remain locked.
