Recovery Key

Overview

The key may unlock an encrypted backup, replace a signer, authorize transfer to a safe destination, or activate a contract recovery function. It can be a complete key or one part of a threshold design, depending on the system.

Because recovery keys are rarely used, loss or corruption may remain unnoticed until an emergency. If the key can bypass daily controls, its compromise may be more damaging than an ordinary credential leak. Storing it beside primary keys defeats separation.

Recovery keys should be generated securely, held offline or under stronger controls, inventoried discreetly, and tested through a non-destructive procedure. Access should require documented activation and appropriate approval. After use or suspected exposure, the key and any related policy should be rotated. Recovery documentation must identify the exact accounts, networks, and actions the key controls.

A controlled Recovery Key process moves through detection, containment, claimant verification, approval, restoration, validation, credential or guardian replacement, reconciliation, and closure. For Recovery Key, emergency access should be time-limited and should not silently weaken the authorization policy used during normal operation.

For Recovery Key, important risks include fraudulent recovery requests, guardian collusion, unavailable shares, outdated backups, compromised cloud accounts, missing derivation metadata, untested procedures, and simultaneous loss of primary and backup systems. For Recovery Key, independent storage and periodic exercises reduce correlated failure but introduce their own custody obligations.

Evidence for Recovery Key should preserve incident time, affected identifiers, last known state, claimant and approver checks, backup or share version, actions performed, credentials revoked, assets verified, discrepancies found, and final owner acceptance. For Recovery Key, sensitive recovery material must not appear in the incident record.
