Frequently asked questions
Is my password stored or sent anywhere?+
No, everything is calculated locally in your browser and never transmitted.
Does a high score guarantee my password can't be hacked?+
No tool can guarantee that, but a high score here reflects strong, well-established best practices.
Rather than a vague strength bar, this tool shows exactly which criteria your password meets — length, character variety, repeated characters, and whether it resembles a commonly breached password — so you know precisely what to improve. Everything is calculated locally as you type; your password is never sent anywhere or logged, which matters since checking a real password on an untrustworthy site is itself a security risk.
