A beneficiary needs at least three valid shares to recover the vault.

​
Trusted-contact shares

Trusted-contact shares are first encrypted with a bootstrap key. During activation, the trusted contact re-seals the share to their own key pair and protects the private key with a passphrase.

​
Cold backup share

The cold backup share is intended for offline storage. It is displayed during setup and should be printed or saved outside the app.
If you close the setup session before saving the cold backup, the app cannot display the same backup share again. Rotate credentials to regenerate recovery shares.
