Abstract: A method includes receiving, from a user, a request to authenticate. The authentication request may include a user id. The method may also include verifying the user id. The method also includes generating a request for a one-time graphical pattern. The method further includes transmitting the request for the one-time graphical pattern to a server and receiving, from the server, the one-time graphical pattern. The method includes transmitting the one-time graphical pattern to the user and prompting the user to input the graphical pattern. The method may also include receiving the inputted graphical pattern from the user and determining whether the inputted graphical pattern matches the transmitted one-time graphical pattern sent to the user. If the inputted graphical pattern matches the transmitted one-time graphical pattern sent to the user, the method may include authenticating the user.
