Frequently Asked Questions
How is password strength calculated?
We analyze entropy, length, and character variety (uppercase, lowercase, numbers, symbols) to estimate how resistant a password is to brute-force attacks.
Is my password sent to your server?
No. The password strength and crack time are calculated entirely in your browser using JavaScript. We never store or transmit your passwords.
What makes a password strong?
A strong password is at least 12 characters long and includes a random mix of letters, numbers, and symbols. Ideally, use a passphrase of random words.
