I've got KeePass, but I haven't used it remotely as long as I've used many websites. Also, I don't have my KeePass DB in Dropbox, so I can't access it from other computers.

More than that, I'd rather not put my KeePass DB on someone else's machine in the first place. But I'll easily trust strange computers with a password for some crappy forum.

There's always something you risk compromising. I prefer some forum account to be compromised.
