Having the means for each spouse to get the others passwords can be pretty essential when dealing with critical emergencies and death.

I wa actually thinking about this. After I had a password breach, I wanted to setup a password manager. I wanted something. That I could host locally and access across my VPN. I also thought it would be neat to have a Deadman switch built in to it, where it pings you at set intervals and asks you to just hit a button to confirm you are alive. If you miss a certain number of pings consecutively, then it emails your specified backup contacts and has allows them to access your passwords.

Is this anything anyone here is interested in? Or does it exist already?
