Physical Key Redundancy

Physical key redundancy refers to the practice of maintaining multiple physical backups of private keys or recovery phrases. These backups are stored in geographically dispersed and secure locations to prevent loss due to fire, theft, or natural disaster.

Without redundancy, the loss of a physical key could result in the permanent loss of all assets protected by that key. This is a critical aspect of disaster recovery planning for both individuals and institutions.

Proper redundancy involves using secure storage methods like metal plates or fireproof safes. It must be balanced with security to ensure that the backups themselves do not become a target for theft.
