QuorumPonyOpen source key backup
Split a key into cards. Any few rebuild it.
QuorumPony turns one secret into a set of backup cards. Gather a few to recover it. A single card on its own reveals nothing.
What it protects
For the secrets you cannot afford to lose, and should not keep in one place.
- CRYPTO Wallet seed phrases and private keys
- IDENTITY PGP, SSH, and age private keys
- ACCESS Password manager recovery codes
- ROOT The master key behind your other backups
Features
Everything happens on your device.
Split a secret
Turn text or a key file into a set of cards. You choose how many to make and how many it takes to recover.
Recover anywhere
Scan each card's QR code or type its printed code. Gather enough and the original comes back.
Check a card
Confirm a stored card is intact and which backup it belongs to, without rebuilding the secret.
Printable cards
Export every card to a clean PDF. Print them, store them apart, or hand them to people you trust.
Fully offline
No account, no sync, no server. QuorumPony never sends your secret anywhere and keeps no copy of it.
Open source core
The cryptography is public under Apache 2.0. The security is something you can read and verify, not just trust.
Biometric lock
Lock the app with Face ID or Touch ID. Copied secrets clear from the clipboard automatically.
Six languages
English, Spanish, German, French, Japanese, and Portuguese (Brazil), switchable any time inside the app.
No tracking
No ads, no analytics, no in-app purchases. The app collects nothing and asks for no permissions it does not need.
How it works
Real Shamir Secret Sharing, in three steps.
Choose the split
Pick how many cards to make and how many it takes to recover. A common setup is 3 of 5.
Print and distribute
Export the cards as a PDF and store them in separate places, or give them to people you trust.
Recover from a few
Bring enough cards back together, scan or type them, and QuorumPony rebuilds the secret.
