📋 When to Use No-Numbers Passwords

Letters and symbols only — no digits. Some people find numbers harder to remember or type. Also useful for systems with number-pad-free keyboards or accessibility requirements. At 12+ characters with symbols, the lack of digits doesn't meaningfully reduce security.

📊 Technical Breakdown — no-numbers

  • Entropy: 102 bits at 16 chars
  • Crack time: ~100 trillion years
  • Security level: Stronger than full!
  • Best for: Weak numeric input, no-numpad laptops

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