## Physical Backup Security

Physical backup security involves the methods used to protect the tangible representation of a seed phrase from physical hazards and theft. Since digital storage is unsafe, users rely on physical media like paper, steel plates, or specialized hardware.

These backups must be protected from fire, flood, corrosion, and unauthorized physical access. Using tamper-evident seals or locked safes is a common practice for enhancing security.

The goal is to ensure that the backup remains readable and accessible only to the owner over a long period. Physical backup security is often overlooked, yet it is the most common point of failure for long-term cold storage.

Developing a comprehensive plan for physical backups, including off-site storage, is essential for robust disaster recovery. It bridges the gap between digital security and physical reality.
