FAQ
Is this password strength checker free to use?
Yes, this tool is completely free to use with no limits on how often you can use it.
Is my password ever sent anywhere?
No. Your password is analyzed entirely in your browser using JavaScript. It is never transmitted, logged, or stored anywhere — including by this site.
How is the strength score calculated?
The score combines password length and the variety of character types used (lowercase, uppercase, numbers, symbols), then subtracts points for common, easily-guessed passwords, sequential characters (like "abc" or "123"), and repeated characters (like "aaa").
