Over time , I want to generate a FreeBSD live CD/DVD with root/user
password entered on boot ( i.e. , no prerecorded passwords ) from a 2D bar
code or from a USB stick or from an SD card with sufficiently long length
defined in the kernel routines .

This feature also may be used for remote logins .

Such a long password generated by a program by random character selection
from a character alphabet  is impossible to estimate .


This "password name length" feature may also be considered along side with
"user name length" .
