Claim 8:
9. A lock system that performs a two factor authentication process, the lock system comprising:
an electronic locking device including:
an electronically controllable locking mechanism;
a memory configured to store a first factor;
a wireless transceiver; and
a processor configured to:
perform a first factor authentication step, which includes (a) acquiring a first factor input and (b) determining if the first factor input matches the first factor;
perform a second factor authentication step, which includes (a) acquiring an encrypted package via the wireless transceiver, (b) decrypting the encrypted package to retrieve a user key, (c) receiving an encrypted command via the wireless transceiver, and (d) decrypting the encrypted command using the user key to generate a decrypted command; and
perform an action associated with the decrypted command in response to (a) the first factor input matching the first factor and (b) successfully decrypting the encrypted command in the second factor authentication step;

wherein the two factor authentication process is at least partially performed between the electronic locking device and a user device; and
wherein, during a prior communication session between the user device and the electronic locking device, the processor is configured to:
receive the encrypted package from the user device via the wireless transceiver;
decrypt the encrypted package to retrieve the user key;
receive a second encrypted command from the user device via the wireless transceiver, the second encrypted command including a first factor upload command;
decrypt the encrypted command using the user key to generate a second decrypted command including the first factor upload command; and
acquire and store the first factor based on the first factor upload decrypted command.
