## What it does

Estimate how much work a password represents by measuring its entropy, assuming a specific number of guesses per second, and reporting how long a cracking rig would need. It is an estimate with stated assumptions rather than a verdict, which is the honest way to present this.

## Use the tool

## Questions

### Why does my password score badly?

Usually because it is short, or built from a predictable pattern. Length adds entropy far faster than swapping letters for symbols, so a long passphrase nearly always beats a short complicated string.

### Is my password sent anywhere?

No. The estimate is computed in the page and nothing is transmitted.
