Allow me to plug my own product: https://padloc.app The new version (currently in beta) has a "Family" plan which is perfect for this. We're also planning to introduce a "dead man's switch" feature that will grant access to selected family members or friends if you haven't logged into your account for a while. Shoot me an email at [email protected] if you're interested in signing up for the beta!
