I use KeePassX, because it works on all desktop OSs, including Linux. It is pretty good. Too bad there's no iPhone version.<p>As a side note, one feature I'd like to see in my password manager software. Say, I suspect that someone might have stolen my passwords db and now owns all the passwords for the websites. I wish I could click one button and the app would do all the job of changing those passwords both in the database and on the websites for me.
