  How many times have you changed your password just because you forgot it?
  Well, you are not alone. In todays security requirements, passwords need
  to be secure and difficult to break. Passwords need to be secure, sure,
  but they can also be easy to remember. Follow up this XKCD article for more
  information - http://xkcd.com/936/

  This does exactly what the picture predicts. You can use this in your Ruby
  applications (Ex: Rails, Sinatra) or standalone if you install the gem (as
  you have done here).

  Wish you all the best keeping things secure.
