I would not be all that surprised if there was really a truley paranoid person that did have a locked briefcase with handcuffs.. and you are right it would pick up the girls.. so maybe I should try it somtime..

Well, leaving aside the issue of using handcuffs to pick up chicks ...

As root, doing "passwd -d userid" should remove the user's password. I've used "passwd -df" to allow users who have forgotten passwords to login on Unix boxes (the "f" makes them immediately pick a new password, so you don't want that).

Testing just now with a second box on my home network running Fedora, I removed a user's password and could log in as that user with just the username, no prompt came for a password. Of course doing that means that you'd better not allow any network access from the internet...such as ssh. I also did a second short experiment and ssh'd from another box as that user. I WAS prompted for a password, but could give ANY password, and log in.

Oh of course if you were using SSH or something like that.. then no DO NOT set it up where you could type in ANY password... and speaking of that.. you have to type in some sort of password right? Well then why no just set a password that the user can use? I mean the user will have to type in something... the user password you set could be something really easy..
