A method for starting a motor vehicle includes recognizing an engine on event of the motor vehicle at a powertrain control module in communication with a vehicle bus system operatively disposed in the motor vehicle. In response to recognizing the engine on event, an authentication request is transmitted from a verification module to a device having an electronic pattern-entry user interface. The method further includes receiving an entered pattern entered on the electronic pattern-entry user interface, and recognizing, by an authentication system, that the entered pattern is an authenticated pattern. In response to the recognizing that the entered pattern is the authenticated pattern, an authenticated engagement command is transmitted to the powertrain control module to instruct the powertrain control module to enter into an engaged state, the engaged state electrically enabling the powertrain control module to provide tractive power to a vehicle drive wheel.
