// About this tool

Check whether a password is strong enough before using it. The tool scores length, character variety, and repetition, then estimates how long an offline attack might take.

// How to use it

  1. Type or paste the password.
  2. Review the strength score and entropy.
  3. Adjust length and character variety as needed.

// Frequently asked questions

Is the password sent anywhere?

No. Analysis happens locally in the browser and the value is not stored.

Is the crack-time estimate exact?

No. It is a rough estimate based on entropy and a fixed guessing rate, not a real attack.
