RndPhrase

RndPhrase is a small add-on that will transform your regular passwords into secure per-domain passwords.
It does so on-the-fly without storing the passwords, or interrupt your browsing experience.

Why?
The main advantages of this approach is:
1) The password is randomized and thereby very hard to guess.
2) Two sites do not share passwords. If one site is hacked and its passwords leaked, it has no effect on your accounts on other sites.

Usage
First, configure a seed for RndPhrase through the add-on settings.
Second, press '@' in a password box before entering the password to activate RndPhrase.

Examples
You can try the system using the web-based version at:

google.com: pdtstnvtrzzc4zxj
twitter.com: wtt1q7ssal3mcjqt
(generated using empty seed and password)
