1. A method of authentication using at least two user devices of an associated set of user devices, the method comprising:

  • registering each user device of an associated set of user devices with an authenticator computing device, wherein each of the user devices of the associated set of user devices are registered to at least one user;

    receiving, at the authenticator computing device, a request to access a resource from one user device of the associated set of user devices, wherein the one user device requesting access to the resource is registered to more than one user;

    generating an authentication challenge at the authenticator computing device in response to the request;

    transmitting the authentication challenge to one user device of a subset of user devices of the associated set of user devices registered with the authenticator computing device, wherein the subset of user devices comprises at least one user device other than the one user device requesting access to the resource;

    transmitting the authentication challenge from the one user device of the subset of user devices to one or more other user devices of the subset of user devices;

    generating at least one response to the authentication challenge at one or more user devices of the subset of user devices;

    transmitting the at least one response to the authenticator computing device;

    determining, at the authenticator computing device, if the at least one response constitutes a valid response to the authentication challenge; and

    granting any one or more of the user devices of the associated set of user devices registered with the authenticator computing device access to the resource if the at least one response received at the authenticator computing device constitutes a valid response to the authentication challenge.
