Claim:
A method of configuring an authentication personal identification number on a headset, comprising: providing a first application on a device configured with a human machine interface; providing a second application on the headset; configuring a personal identification number access information on said headset using said first application and said second application, comprising: establishing a secure communication link by completing challenge response interaction sequences between the headset and the device, using a currently prevailing personal identification number; generating an autonomous request from the headset to configure a new authentication personal identification number based on a pre-set timeout for said currently prevailing personal identification number; generating a new authentication personal identification number at the device based on one of a user input at the device and a user selection from a list of permitted personal identification numbers stored in the device; transmitting said new authentication personal identification number from said device to said headset for configuring the new authentication personal identification number in the headset, whereby said human machine interface of said device acts as an extended human machine interface of the headset, wherein said transmission occurs through said established secure communication link; and automatically enforcing reauthentication using said new authentication personal identification number; whereby said reauthentication using said new authentication personal identification number enables audio communication between said headset and said device.
