Kyle: A password manager for paranoids.

One point to add for misunderstandings is that listing animal names and passwords mostly protects you from keyloggers.

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.

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.
