1. An external device, comprising:
a memory storing an identifier corresponding to a program bonded implantable medical device and a programming session key;
a recharge circuit;
a far field telemetry circuit; and
a processor configured to:
send a recharge session key to a first implantable device that is not program bonded by the identifier stored in the memory,
receive a second identifier and determine if the second identifier matches the identifier stored in the memory,
send recharge energy during a recharge session to the first implantable medical device using the recharge circuit if the second identifier does not match the identifier stored in the memory and is from the first implantable medical device,
exchange information related to the recharge session with the first implantable device using the recharge session key via the far field telemetry circuit while the programming session key remains stored in the memory,
detect user input to compare the second identifier and the identifier stored in the memory to satisfy security concerns;
ignore the request if the second identifier is different than the identifier stored in the memory,
provide the user access to secure features if the second identifier is stored in the memory; and
exchange, at a time after the recharge session, programming information with a second implantable device using the programming session key via the far field telemetry circuit.
