Additional USB Bluetooth Proximity Sensor
GateKeeper USB Bluetooth wireless proximity sensor (dongle) is one part of the GateKeeper 2FA system to keep your computer secured. It acts as the Bluetooth receiver for your computer. GateKeeper supports multiple dongles per computer to enhance the signal. If you have more computers than users, you can buy additional USB receivers to enable GateKeeper access to those computers. Even if your computer has Bluetooth, we highly recommend using additional proximity sensors to boost your computer's signal coverage to more accurately detect tokens.
GateKeeper also supports internal Bluetooth receivers on Win 10 computers. However, the performance of the software will always be significantly higher with the GateKeeper USB sensor than with the internal Bluetooth receiver.
