Frequently Asked Questions
What makes a password strong?
Length (12+ characters), mixed case (uppercase and lowercase), numbers, and special characters. Each additional character type exponentially increases the number of possible combinations an attacker must try.
Is my password sent to any server?
No. All analysis happens in your browser. Your password never leaves your device. This page does not make any network requests with your password data.
Why is my password rated as weak?
Common reasons: too short (under 8 characters), only lowercase letters, no numbers, or no special characters. Follow the feedback suggestions to improve each weak area.
