Another problem is keeping your backup passwords in sync with your day to day use passwords, especially if you're not going to die to 40-80 years.<p>Probably the best solution is to have something like 1Password set to automatically manage passwords, encrypted with a master password, and then disclose only enough information to get to the daily-use 1Password. Disclosing a single password like that is probably better accomplished in a paper will, stored with a lawyer/executor.<p>Although there's also some value in an "I'm dead" script which deletes porn, porn passwords, information about your affairs, criminal activity, compromising photos involving porn and crime and drugs, the Guatemalan second family you support, etc., before turning over things like facebook passwords to next of kin.
