I use a password to login... When I leave the computer it locks correctly but when returning the screen will come back on and I still have to enter my password. If I remove my password there is no real locking taking place, anyone can just come up and jiggle he mouse to gain entrance. Is there anyway to authenticate by the device's MAC address to unlock and if the device is not present to use a password instead?
Im looking into pam_blue - http://pam.0xdef.net/index.html
This may allow user authentication needed by device MAC address through bluetooth.
Ill start playing with it this weekend.
