    Frequently asked questions

    Is my password sent to a server?

    No. Strength checking runs entirely in your browser. Your password never leaves your device.

    What makes a password strong?

    Length (12+ chars), mixed case, numbers, special characters, and avoiding common passwords.

    How is crack time estimated?

    Based on password entropy — character set size and length — not actual breach data.

    Should I use this instead of a password manager?

    Use a password manager to generate and store passwords. Use this tool to evaluate passwords you create manually.
