I have to add another vote for Clipperz (http://clipperz.com). I started using it to manage insecure passwords. I tried to use a generic insecure password as others have mentioned above, but I kept encountering slightly different password restrictions that made this very difficult. I think Clipperz is web-based password management done right. Encryption is done in the browser and the javascript code is open source. Only encrypted data is stored on the server, so they can't even get your information. I highly recommend at least checking it out.
