About this tool
ToolAdda's Password Strength Checker uses the zxcvbn engine to provide realistic crack-time estimates across five attack scenarios, with pattern highlighting and breached-password detection. All analysis runs locally in your browser, so your password is never transmitted or stored. It also includes a password generator, passphrase generator, and bulk checking with CSV export.
