Abstract: Systems and methods for multi-factor authentication using graphical passwords. An access request that includes an identifier and which identifies a protected resource is received from a client device. An interface is generated having a plurality of graphical objects for presentation at random locations on a display of the client device as defined by an object map. The plurality of graphical objects include a null object and a set of user-defined objects associated with the identifier that define a graphical password. Input data including an input event for each detected interaction with the interface is received. Each input event identifies a position on the display at which a corresponding interaction was detected. Using the object map, it is determined that the input data satisfies the graphical password. Access to the protected resource is granted in response to determining that the input data satisfies the graphical password.
