I run a web site with over 4500 members (http://www.airforcesecuritypolice.com). However, I do not have access to passwords. I sometimes wish that I did, since I have a lot of members that get deployed and when they come back, they have forgotten them and email me for them. I simply set up a dummy password for them to get them back on track.

I guess that it would depend on the type of web site as far as if the administrator knows the password you chose.
