List User Passwords

Hi. I have somewhat of an extranet set up for a client, and the client has a list of user in the admin. The client wants to be able to see the user passwords in the administrative area. I have started to try and figure out how to do this by putting the following in one of my templates:

<?php $password = ( $userdata->user_pass ); ?>
                Password: <? echo $password ; ?>
                Username: <? echo $userdata->user_login ; ?>
                <? } ?>

However, this outputs the encrypted version of the password. I have done some research on this, and pretty much have come up with the answer that “That’s just the way WordPress works.” So I am just hoping someone has had a similar issue or could offer a solution. The main goal here is to be able to allow the client to see the user’s passwords in the admin area, so they don’t have to keep some kind of excel file with the passwords.
