Password strength checker — how long to crack?
Type a password to see its strength score, time to crack and tips — checked on your device, never sent.
About Password strength checker
Type a password to estimate how many guesses an attacker needs, with penalties for common passwords (123456, password), keyboard runs (qwerty), repeats, dates and dictionary words, shown as online (rate-limited) and offline (billions of guesses a second) crack times.
The password isn't sent anywhere, but don't type real passwords into sites you don't trust. Best practice: long, random and unique for every site.
