Cygen (based on SuperGenPass)

I love this extension and have used it for a couple of years now. The only thing it lacks in my opinion is the option to create saved profiles, and the option for the salt to persist across resets. Having to enter it every time the stored data resets makes it a lot less useful in my opinion.

ill give it a try. looks real good so far

A very good implementation of the SuperGenPass aglorithm, with a great UI and secure! As for the other comment, it uses a "master" Password to generate passwords for each site, it does not release your user-chosen password.

The mantra behind the original SuperGenPass is that you never have to store the password. Since this stores your password (even if only for a day), it's not as safe as the original bookmarklet.
