1. A method comprising:

  • receiving a request at a server from a client device via an access point, the request received via a first network, wherein the request identifies a network resource available from a second server via a second network, wherein the second server is distinct from the server, and wherein the second network is different than the first network;

    responsive to the receiving the request, determining, at the server, whether access to the network resource is conditioned upon authentication;

    transmitting an authentication request from the server to the client device in response to determining that access to the network resource is conditioned upon authentication, wherein the authentication request includes an authentication seed;

    receiving authentication information at the server from the client device, wherein the authentication information includes a first result of a one-way hash function based on the authentication seed;

    computing, at the server, a second result of the one-way hash function based on the authentication seed;

    performing a first comparison of the first result to the second result;

    in response to a first determination based on the first comparison that the first result matches the second result, determining a location associated with the client device based on the access point;

    determining whether the client device is permitted to access the second network from the location; and

    in response to a second determination by the server that the client device is permitted to access the second network from the location, enabling, via the server, the client device to access the second network.
