πŸ” Background Context

From an inheritance planning perspective, assume you already have a geographical distribution of seed phrases and passphrases which would allow a family member to recover funds. Assume multisig, Seed XOR, a combination, or something similar. The specifics are irrelevant to this thought experiment, just assume effort has already been put in to distribute backup information for an inheritance-based recovery plan.

πŸ’‘ Proposed Feature

It would be great to be able to pass along additional encrypted notes that could be decrypted with one of Coldcard's BIP-85 deterministic passwords. This way, in a situation where a family member has recovered the setup, they could load the additional encrypted note(s) into their Coldcard and read them. Or just decrypt the note(s) on their computer by entering the BIP-85 password (BIP-85 password #5 for example).

πŸ“ Current Implementation

Currently Coldcard Q does allow for typing notes on device and encrypting them. However, exporting these in encrypted form means generating a new set of backup words. This means every time you'd want to add to, or alter your inheritance information (add a new 2FA secret, alter an instruction, etc.), you now have a new set of words that that needs backing up. Being able to encrypt these using BIP-85 determinist entropy from the existing seed phrase / passphase combination that is already geographically distributed would be a huge improvement.

Another layer of complexity can cause funds to be lost forever

This isn’t impacting how funds are stored at all. Just making use of the fact that effort has already gone into securing funds, might as well use that same security to encrypt some additional notes.

Encrypted breadcrumbs sound useful. It's hard to gauge the UX loss relative to the incremental security gain but that's the case with many of these things.

Was just discussing this with my son.
My seed phrases are encrypted by my own system
And I've been making sure if something happens to me, he knows how to unencrypt and recover if needed
Sounds like a cool idea

Yes and I already have a cold card, so I guess the first option
