📋 When to Use 16-Character Passwords

16 characters is the gold standard for password security. With all character types, it would take billions of years to brute-force. Use this for critical accounts: primary email, banking, password manager master passwords, and administrative access. This is what security professionals use for their own accounts.

📊 Technical Breakdown — 16-character

• Entropy: 91 bits (full) / 76 bits (letters+digits)
• Crack time: ~250 billion years
• Security level: Gold Standard
• Best for: Banking, admin, crypto wallets

All calculations assume 16-character with mixed character types. Actual security depends on specific character selection.
