I've seen a few of those tools that send passwords periodically (unless you stop it) to designated people. Like you said, that's subject to abuse.

I feel like there needs to be a crypto solution, like a smart contract of some kind that is trustless. The good thing about Hive is the wallet is public anyway, so what is contained there is clear. The information is also out there for would be claimants to educate themselves on the value of the token and how to cash it out, or continue staking, or whatever. The issue is how to grant access.

If only Skype worked in heaven (or hell) sigh.
