Seed Phrase Security & Recovery
A seed phrase written on paper is vulnerable to fire. Stamped on metal, it survives fire and flood. Split using Shamir's Secret Sharing, no single piece reveals the full phrase. The level of protection should match the amount of Bitcoin.
Seed phrases are the master keys to your Bitcoin wallet. Their security is paramount - anyone with access to your seed phrase has complete control over your funds. Proper storage and handling of seed phrases is one of the most critical aspects of Bitcoin security.
Seed phrase protection methods:
- •Physical backup: Metal plates resistant to fire and water
- •Encrypted storage: Password-protected digital backups
- •Shamir's Secret Sharing: Split seed phrase into multiple shares
- •Geographic distribution: Store backups in different locations
- •Redundant formats: Multiple backup methods for same seed
Recovery procedures:
1. Test recovery regularly: Practice restoring from backups 2. Verify completeness: Ensure all words and order are correct 3. Use offline methods: Never enter seed phrases online 4. Document procedures: Clear steps for emergency recovery 5. Update when needed: Change seed phrases if compromised
For most people, a metal backup plate in a home safe is sufficient. For larger amounts, consider geographic distribution — multiple locations, each with a partial backup.
