Use a Passphrase Carefully
A passphrase (25th word) adds an extra layer but also increases recovery complexity. Use passphrases only if you fully understand recovery implications and manage backups safely.
Backup Strategies
- Write seed on paper and consider a metal backup for fire/water resistance.
- Store backups in geographically separated secure locations (trusted safe deposit, home safe).
- Do not store seeds as photos, cloud notes, or plaintext files.
Firmware & Authenticity
Only install firmware updates via Ledger Live. Verify device authenticity on first setup and check firmware signatures where Ledger provides verification steps.
Pro Tips
- Rotate devices if you suspect compromise — restore from seed to a new hardware device.
- Consider a dedicated air-gapped machine for large, infrequent operations (advanced users).
- Use multi-sig setups for organizational funds where appropriate.
