Split the key to anything across five small objects. Give them to people you trust. Any three, together, can open it. Two can't learn a thing, and no company holds a copy.

One way to use it
Your letters, passwords, files or instructions are encrypted and stored wherever you like. Only the key gets split.
Each piece goes on a tag inside a small object: a keychain, a book, a frame. You hand them to people you trust.
When the time comes, any three holders tap their objects to one phone. The key comes back, and nobody needed our permission.

As widely reported in 2021, programmer Stefan Thomas lost the paper with the password to a drive holding keys to 7,002 bitcoin. The drive allows ten guesses, and he had used eight.
Cointelegraph on the New York Times report, 2021QuadrigaCX's customers were told only its late founder could reach their money. Ontario's regulator later found the collapse came from his fraud, with about C$169 million in client losses. A sole keyholder is also a place to hide.
Ontario Securities Commission staff review, 2020Adi Shamir published secret sharing in 1979. Trezor uses it today so crypto owners can split a wallet backup. Almost nobody has made it simple enough for a family or for documents.

Our view, not a citation.Made up to show the idea. These are not real customers or results.
Three siblings bring their objects to the kitchen table. Out come the accounts, the letters, and what their mother wanted done.
The master credentials need two founders and the lawyer. No one person can act alone or lock everyone else out.
Sensitive files stay sealed. If something happens, three colleagues in different places can open them together.
That's what we're trying to learn. No need to share anything sensitive, a rough description is plenty. We read every answer, and the clearest needs get the first kits.
