An electronic device, comprising:

• a processor and memory storing one or more programs for execution by the processor to cause the processor:
• provide to a remote service a first authentication code and information identifying a second electronic device that is associated with the first authentication code;
• receive a second authentication code only at the electronic device from the remote service, wherein the second authentication code is based on the first authentication code and the information identifying the second electronic device, wherein the second authentication code is configured to be utilized by the second electronic device to access the electronic device and establish one or more communication channels by which data content is transferred between the electronic device and the second electronic device;
• and
• after receiving the second authentication code from the remote service, transmit the second authentication code from the electronic device to the second electronic device to enable the second electronic device to access the electronic device.

A non-transitory computer-readable medium having computer executable code stored thereon, the code comprising instructions to:

• cause a processor of a first electronic device to provide to a remote service a first authentication code and information identifying a second electronic device that is associated with the first authentication code;
• cause the processor to receive a second authentication code from the remote service, wherein the second authentication code is based on the first authentication code and the information identifying the second electronic device, wherein the second authentication code is configured to be utilized by the second electronic device to access the electronic device and establish one or more communication channels by which data content is transferred between the first electronic device and the second electronic device;
• and
• cause the processor to after receiving the second authentication code from the remote service, transmit the second authentication code from the electronic device to the second electronic device to enable the second electronic device to access the electronic device.
