A method of authenticating a user of a computing device is proposed, together with computing device on which the method is implemented. A plurality of objects is displayed on a display screen. The plurality of objects includes at least objects that make up a sequence of objects pre-selected as the user's passcode. In response to a trigger signal an image of the user's face is captured while looking at one of the objects on the display screen. A determination of which object is in the direction of the user's gaze is made from the photograph and whether or not the gaze is on the correct object in the sequence of the passcode. This is repeated for each object in the sequence of the passcode. |
