A short companion for Password Strength: when it is useful, what it expects, and what to check before using the result.
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
Open Password Strength, add the input the tool asks for, run it, and check the output before using it elsewhere.
Input and output

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.
