Not my idea. You can have a lawyer that has access to all your passwords, and designate a list of trusted people that can access them in an emergency.

If something happens, your friend calls the lawyer. The lawyer calls the other friends and if enough concur releases your passwords.

Depending on how technical you and your inner circle is you can even have whatever secret the lawyer holds encrypted and a key preshared with your friends so that the lawyer cant use it or the secret is irrelevant if it leaks.

This is of course more relevant in a you drop of the face of the earth, or you are wrongfully or rightly arrested kind of scenario.
