Hi, i'm the developer. :)<p>One point to add for misunderstandings is that listing animal names and passwords mostly protects you from keyloggers.<p>Even someone knows your master-key and all the details you use, it should monitor what you copy-pasted. Otherwise try/fail would be notified on limited environments if the attacker is not lucky enough.
So instead of storing passwords it has a repeatable process for generating hashed passwords for a given host+account+port+master key?<p>One problem I see is that your favorite animal might result in a password that isn't allowed for a given site. But I assume the paranoid target user would never use such a site.
I like this. It's similar in nature to what I'm looking to do with blot.pw (more information at <a href="https://github.com/stuartpb/hashblot/wiki/About" rel="nofollow">https://github.com/stuartpb/hashblot/wiki/About</a> )
