Password Crack Estimator — Math-Based Prediction, One Number

Type a password to get a single crack-time prediction, computed directly from its mathematical entropy — a fast, no-frills estimate. For a breakdown across multiple attack speeds (online throttled vs offline GPU), see Crack Time Estimator, which splits the same underlying math into scenario-specific numbers.

How to use Crack Estimator

1. Type your password.
2. Read the predicted crack time.
3. For a scenario breakdown by attack type, use Crack Time Estimator instead.

Frequently asked questions

How is this different from Crack Time Estimator?

This gives one overall estimate from the entropy math directly; Crack Time Estimator breaks the same underlying calculation into separate numbers per attack scenario (online, offline, GPU cluster).

What assumption does the single estimate use?

It uses a representative offline attack speed as the baseline — for the online-vs-offline breakdown, use Crack Time Estimator.

Is my password sent anywhere?

No. The estimate is computed entirely in your browser.
