And for those of us who aren't wealthy enough to have two different attorneys on retainer, giving your spouse the encrypted password store along with the key to a safety deposit box containing the decryption key would have to do.
Personally, my wife would wonder why I'm going to so much trouble to keep my passwords secret from her until I die; but then my personal password store is for services we share like banking, and any passwords she doesn't know are benign things like my email addresses and various website logins that wouldn't matter anyway when I die. Of course I also have my work passwords (I'm the IT manager), but my supervisor and the company owner each have a secured store of all of my work passwords as well, plus the master password to access them, in the event something happens to me (or I'm just on vacation for a week and temporarily unreachable when access is needed).
This is more of a thought experiment, but would also serve as a decent backup in case of natural disaster, house burning down, etc. As for safety deposit boxes, those can be closed out for nonpayment, bank branches will shut down, etc. Not the best hands off long term solution. An attorney will let you know if there's an issue because it's their ass on the line if they don't.
