A system and method of anonymous authentication is described. In operation, the authenticator receives a request to access a resource from one of the user devices of an associated set of user devices, wherein each of the user devices is registered to at least one user requesting access to the resource registered to at least two users. The authenticator generates and transmits an authentication challenge in response to the request to a subset of the user devices. A user device subsequently generates and transmits a response to the authentication challenge to the authenticator. The authenticator determines whether the responses received from the one or more user devices constitutes a valid response and grants any one or more of the user devices of the associated set of user devices access to the resource if the responses received from the user devices constitutes a valid response to the authentication challenge.
