SplitKey
A private, post-quantum vault for the documents you can't afford to lose or leak — statements, contracts, deeds, and personal records. This Mac and a Face ID-verified iPhone must each contribute a share before anything in the vault is released. No single device, and no one else, is ever enough on its own.
Authorize a signer
Link a Face ID-protected iPhone once — it becomes your co-signer, required to approve the release of every document you place in the vault.
Hackathon research prototype — not a certified secure element, not formally audited. See the README for the full threat model and limitations.
