Abstract
A system for bidirectional two-factor remote user authentication includes a workflow engine comprising one or more processors and at least one memory element for storing instructions. The system further includes a client device with one or more processors, a display, and a user login interface. The workflow engine generates and encrypts one or more login identifiers, which is visually encoded as an authentication image and displayed on the terminal's display. An electronic device, also connected to the workflow engine, includes a password, a display with a graphical user interface, one or more processors, and at least one memory element. The device's authentication identifier reader decrypts the one or more login identifiers from the authentication image and compares it with the password to determine a match. Upon a match, the device transmits an authorization for the login request to the workflow engine.
