An approach is described for authenticating a user. An associated method includes displaying a dynamic image on a display screen, detecting a user interaction with the displayed image, and detecting a duration of the detected user interaction. The method further includes comparing the detected user interaction and the detected duration with a stored user interaction and a stored duration. The method further includes authenticating the user upon determining that the detected user interaction matches the stored user interaction and the detected duration matches the stored duration. In an embodiment, the method further includes transmitting the detected user interaction and the detected duration to a remote device. In such embodiment, the method step of comparing the detected user interaction and the detected duration with the stored user interaction and the stored duration is performed by the remote device.
