📋 When to Use 20-Character Passwords

20 characters provides maximum practical security. Brute-forcing would take longer than the heat death of the universe. Reserved for encryption keys, certificate authorities, root accounts, and environments where compromise is catastrophic. Overkill for everyday use — but sometimes overkill is exactly what you need.

📊 รายละเอียดทางเทคนิค — 20-character

• Entropy: 114 bits (full)
• Crack time: 2.4x10^21 years (heat death)
• Security level: Extreme
• เหมาะสำหรับ: Encryption keys, API tokens, CA

All calculations assume 20-character with mixed character types. Actual security depends on specific character selection.
