The present disclosure relates to a visual display system for manipulating images of a real scene using augmented reality. In one implementation, the system may include at least one processor in communication with a first mobile device; and a storage medium storing instructions that, when executed, configure the at least one processor to perform operations. The operations may include receiving a request from a mobile device to access an account of a user, receiving a first image depicting a real scene from an image sensor of the mobile device, receiving a selection of a virtual object, receiving an augmented reality image comprising the virtual object overlaid on the first image, comparing the augmented reality image to one or more stored augmented reality images, authenticating the user based on the comparison, and authorizing access to the user account based on the authentication.
