What is Password Strength Checker?

Password strength checker analyzes passwords and evaluates their security level based on various criteria.

Evaluation Criteria

  • Length (minimum 8, recommended 12+)
  • Character variety (upper, lower, numbers, symbols)
  • Common pattern detection
  • Dictionary word checking

Strength Levels

  • Weak: Easy to crack
  • Medium: Moderate security
  • Strong: Good security
  • Very Strong: Excellent security

Frequently Asked Questions

Is the analysis local? Is my password uploaded?
Strength scoring runs entirely in your browser; nothing is sent anywhere. The checker applies heuristics — length, character variety, common patterns (keyboard walks, repeats, dictionary words) — measuring structural resistance to cracking.
Does a "strong" rating guarantee safety?
Structural strength is necessary but not sufficient: a patternically strong password that appeared in a breach database is still dangerous. Combine with breach lookups (like haveibeenpwned) and unique passwords per site.
Why does "Password1234@Ab" score low?
Crackers try dictionaries far earlier than brute force: common words, common substitutions (a→@, s→$), trailing digits are round one. Pattern recognition downgrades these structures — which is exactly the value over older checkers that only counted length and character classes.
