libpam-blue - 0.9.0-3+b1 main

pam_blue is a dynamically loadable binary object for the PAM security
framework in Linux. It is presented as an extension for the common PAM
modules, gives the user the ability for authenticate via a
Bluetooth-compatible device like a cell phone or other bluetooth
dongles (e.g. epox-presenter). Due to the fact that a whole part of
the Bluetooth stack is implemented in hardware-side it is relatively
difficult to change the Bluetooth hardware MAC address which makes
this module more secure.
