A non-transitory machine-readable medium storing instructions that, when executed by a mobile electronic device, cause the mobile computing device to perform actions comprising:

• receiving, by the mobile electronic device, a request from a server system to approve a session for a second electronic device to access a logical resource;
• in response to receiving the request, initiating, by the mobile electronic device, communication with the second electronic device over a wireless communication link using a radio of the mobile electronic device;
• receiving, by the mobile electronic device, data from the second electronic device over the wireless communication link, the received data from the second electronic device indicating a session identifier;
• and
• after receiving the data from the second electronic device, providing, by the mobile electronic device, a response to the server system that (i) indicates approval of the session for the second electronic device to access the logical resource and (ii) indicates the session identifier received from the second electronic device over the wireless communication link.
