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.
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.
