aboutTool

Password Strength Analyzer provides a deep analysis of password complexity and security. Moving beyond simple length checks, it calculates cryptographic entropy and estimates brute-force cracking time to offer professional security guidance.

howToUse

  1. Enter the password you wish to analyze
  2. Review the security grade and entropy score
  3. Check the estimated time required for a brute-force attack
  4. Follow the suggested tips to strengthen your password

features

  • Real-time cryptographic entropy calculation
  • Brute-force crack time estimations
  • Detection of common words and patterns (e.g., "1234")
  • Leak database comparison heuristics
  • User-friendly security scoring system
  • Secure, private local-only execution

faq

What is the entropy score?

It measures the randomness of a password; higher entropy scales the difficulty of hacking exponentially.

Is my password sent to a server?

No, all logic runs locally in your browser to ensure your password stays private and secure.

What is a safe score?

Generally, an entropy score above 80 bits is considered highly secure against modern attacks.
