Claim 14:
15. A charging device comprising:
a memory storing instructions; and
a processor communicatively coupled to the memory and configured to execute the instructions to:
provide a power signal to a hearing device while the hearing device is within a charging range of the charging device;
participate in an establishment of a primary communication channel between the charging device and the hearing device, and
transmit, based on the establishment of the primary communication channel, authentication information to the hearing device by way of a secondary communication channel that allows for communication only over distances that are below a threshold distance, the authentication information usable to perform an authenticated pairing procedure for the primary communication channel;

wherein the processor is configured to transmit the authentication information to the hearing device by way of the secondary communication channel by modulating the power signal.
