Kyle: A password manager for paranoids. (opens in new tab)

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.
