If you decide to use this solution, you'll have to change your passwords for each site where you want to use passwords generated by SuperGenPass. You can first try it with an unimportant site to see if you like it. Also you'll have to stop storing passwords in your browser or other password managers.
How will you use it?
* type the username and the master password when you log in
* click on the bookmarklet [extra-click]
* click on "Populate" [extra-click]
* submit the form
So two extra-clicks, no required software, no stored password and just a bookmarklet that could be easily stored on a USB drive (there's an alternative page for mobile phones). And, best of all, you can use a single password for all the sites that need one.
