Password Strength Tester
See how long a password would take to crack, with feedback. Everything stays on your device. Runs entirely in your browser, nothing is stored.
How this works
The open-source zxcvbn engine runs inside your browser. It looks for dictionary words, names, keyboard patterns, dates and repeats, then estimates how many guesses an attacker would need.
What we never see
Your password. It isn't sent, saved or logged anywhere; closing the tab clears it.
