Password Strength Checker
Find out how strong a password really is — it's checked on your device and never sent anywhere.
● 🔒 Your password is analyzed only in your browser. It is never stored, logged or sent anywhere.
How it works
Simple rules like “one uppercase and one symbol” say little about real strength. Attackers try common passwords, dictionary words with substitutions (p@ssw0rd), keyboard patterns (qwerty, 123456), dates and repeated characters first. KadiTools looks for these patterns, estimates how many guesses an attacker would need, and converts that into time for three attack scenarios.
The best passwords are long and random: a passphrase of four or five random words, or 16+ random characters from a password manager.
FAQ
Is it safe to type my real password here?
The check runs entirely in your browser and nothing is sent. Still, as a habit, prefer testing a similar password rather than the exact one.
