How Long to Crack Your Password?

Type a password and watch the estimated time-to-crack change as you type — under three different attacker scenarios. It all runs in your browser; nothing is sent anywhere.

Online attack, rate-limited
e.g. trying a login form (10 guesses/sec)
Stolen database, fast GPU
weak hashing, ~100 billion guesses/sec
Well-funded cracking farm
~100 trillion guesses/sec

These are estimates based on the variety and length of characters, with common passwords penalised. They assume an attacker who does not already know your password from a breach — which is the real reason to never reuse one. Generate strong ones with our password generator.
