Abstract
A method for entering a passcode within a mobile device begins with receiving an indication of a user attempt to access the mobile device. A passcode entry display including a plurality of touch points is generated responsive to the indication. Each of the plurality of touch points includes at least two visual identifiers associated therewith. The passcode entry display is displayed on an interface of the mobile device and the passcode is received responsive to user selection of a sequences of the plurality of touch points associated with a predetermined sequence of at least one of the visual identifiers. The arrangement of the at least two visual identifier associated with the plurality of touch points of each passcode entry display differs from an arrangement of the at least two visual identifiers in a previous and a subsequent passcode entry display.
