A method of authenticating a user of a computing device is proposed, together with computing device on which the method is implemented. In the method a modified base image is overlaid with a modified overlay image on a display and either the modified base image or modified overlay image is moved by the user. A security level requirement is assigned and positive authentication is indicated in response to the base image reference point on the modified base image being aligned with the overlay image reference point on the modified overlay image after the moving in a manner that meets the security level requirement. |
