I came here hoping that the emergency sheet feature was an implementation of Shamir Secret Sharing. That would allow you to give a few sheets to trusted people, which they could combine to reveal your password.
The same parameters input into two online SSSS generators: 3 parts( 2 reqd), secret=hackernews yield different parts.
I want to make it easy to recover. Using the same tool to store the passwords and recover the keys simplifies the process.
