Passphrase vs PIN: Advanced Ledger Security

The PIN protects physical device access. The passphrase (25th word) creates entirely separate accounts from the same seed.

The PIN

4-8 digits. Device wipes after 3 wrong attempts. Prevents unauthorized physical use.

The Passphrase

Optional addition to your 24 words. Creates a completely different set of addresses. Not stored on device.

Use Cases

• Plausible deniability: Decoy wallet with small balance; real funds behind passphrase
• Extra security: Even if seed is compromised, passphrase wallet remains hidden
• Multiple wallets: Different passphrases for different purposes

Critical Rules

• Never forget it: There is no recovery. No support ticket, no password reset
• Store separately from seed: Defeats the purpose if both are compromised
• Use 20+ random characters: Short passphrases are vulnerable to brute force
• Test recovery before loading significant funds
