Forcing people to change their password on a regular basis is a bad 
idea, tends to make people choose easier to guess passwords. Do you 
regularly change the locks on your house?

My root password is 16 characters that was computer generated -- not 
worth memorising, if I had to regularly change it!

Example password: q!5H!A:xa$3l%o.y Good luck trying to crack my system 
using it!

If anyone is interested, I can publish the Java program I wrote to 
generate my passwords.
