Passkeys as part of estate planning

Thanks so much for that, 1P_Dave. I'm really fascinated by it all and I love thinking about this topic. Now I'm wondering, I've secured my email accounts with passkeys, so what would I leave for an executor or POA? Should I look into a YubiKey to be stored in a safe with the 1Password recovery code? How long will passwords stick around for services like email or will passwords always serve as a fallback for account recovery? But wait...those are hackable or crackable so I would think service providers will eventually ditch passwords and only want to allow passkeys. How does one recover a passkey with a passkey? 🤔

On a related note, what do you think will become of app-specific passwords? I've secured my Apple ID with a passkey, but several times now I've signed up for a new scheduling service (I'm tinkering and trying things out) and I needed to log in with my password instead. Evidently Apple won't let you create an app-specific password while logging in with a passkey. What do you make of that?
