Frequently asked questions
How is crack time estimated?
Average time = combinations ÷ 2 ÷ guesses per second.
Why do real passwords fall faster?
Words, names and patterns are guessed first, so human-chosen passwords are far weaker than random ones.
Is a password sent anywhere?
No password is entered; only length and character set.
Is my data sent to a server?
No. Everything is calculated in your browser, so what you enter stays on your device.
