Password Strength
How strong is your password?
Runs in your browserAbout
Password Strength checks a password against the zxcvbn algorithm — the same pattern-aware strength estimator Dropbox open-sourced, which catches predictable patterns like keyboard walks and common substitutions that simple length or character-class rules miss — and shows an estimated crack time plus specific suggestions for improving it. The password you type is never sent anywhere; the check runs entirely in your browser, which matters given what you're typing.
