FAQ
How is strength evaluated?+
Entropy (randomness), dictionary word matching, keyboard patterns, character repetition, and common-password databases combined.
What's entropy?+
Randomness measured in bits. 60+ bits is reasonably safe; 80+ is very safe. Increases with length and character diversity.
Which of two passwords is better?+
Generally the longer one with more character types. Side-by-side makes it obvious.
Are passwords sent anywhere?+
No. Everything stays in your browser. Still, avoid pasting production passwords into external tools.
Why is comparison useful?+
Confirms whether changing your password actually improved security. Don't rely on 'feels complex' subjective judgments.
