The certified skyBeacon and tailBeacon feature a unique password secured configuration interface via Wi-Fi.  A user must enter the password to change the device configuration including the aircraft ICAO and callsign.   The password is unique to the device, and once configured, cannot be reconfigured for another aircraft without that password. The password is essentially an anti-theft key, and should be kept secure with aircraft record.  There are no external markings or indications on the skyBeacon or tailBeacon to indicate the password.

uAvionix will be able to provide the password if lost provided proof of purchase can be validated.
