Password Strength Analyzer

Test your password's strength without risking exposure. Our analyzer runs locally in your browser — your keystrokes are never transmitted over the internet.

Safety Notice We added technical measures (autocomplete="off", data-lpignore="true") to prevent browsers or password managers from logging what you type here. Type a test password — ideally not your actual current password.

How This Keeps You Safe

Typing your password into a random website's checker is a major security risk. This tool runs a JavaScript analysis algorithm entirely within your browser tab. No data is sent, logged, or cached anywhere.

What We Check

  • Password length
  • Uppercase & lowercase
  • Numbers & symbols
  • Common dictionary passwords (top 500)
  • Keyboard walk patterns (qwerty, 12345)
  • Date patterns (1990, 2024)
  • Repeated characters
  • Sequential runs
