@77nn @kaia we have individual #KeepassXC vaults, and a shared one called "KeeShare" that has a bunch of shared accounts (e.g. utilities) and other PII (e.g. ID numbers). It sort of works like a symlinked additional vault.
Then, in the safety deposit box -to which we both have access- is a relatively recent copy of both password vaults and their passphrases written down.
Also, my vault requires a Yubikey w/ a configured Challenge/Response.
