📋 When to Use No-Uppercase Passwords

Lowercase, numbers, and symbols — no capital letters. Useful when Caps Lock would cause login failures (some Linux terminal logins, embedded systems). Also helpful for users who primarily type on mobile where shifting is slow. Security impact is minimal because length and other character types compensate.

📊 Technical Breakdown — no-upper

  • Entropy: 97 bits at 16 chars
  • Crack time: ~4 trillion years
  • Security level: Very Strong
  • Best for: Case-insensitive systems, CapsLock

All calculations assume no-upper with mixed character types. Actual security depends on specific character selection.
