What it does
Estimates password strength using zxcvbn - Dropbox’s realistic estimator that models dictionary words, common substitutions, repeats, sequences, and keyboard patterns. Reports a 0-4 score, estimated guesses, crack times, and actionable feedback.
How to use it
- Type or paste a password.
- Optionally list related values (username, site, birth year) so they count against strength.
- Read the score, crack-time estimates, and suggestions.
Examples
password→ Very weak (0) - top-100 common.correct horse battery staple→ Strong (4) - long, uncommon words.
Good to know
- Private: analysis is local - the password is never sent anywhere.
- zxcvbn is far more realistic than naive
