Password Strength Checker
Type a password to see an estimated strength rating and crack time. Nothing you type here is sent anywhere — the check runs entirely in your browser.
How to use this tool
- 1Type a password into the input box (or a similar one — never your real password on an unfamiliar tool).
- 2See its estimated strength and rough crack-time estimate update live.
- 3Use the feedback to spot easy improvements, like adding length or avoiding common patterns.
Frequently asked questions
- Does this tool store or send my password?
- No. The strength estimate is calculated with JavaScript running locally in your browser; nothing is transmitted or logged.
- Why did a long password still get a weak rating?
- Length helps, but predictable patterns (keyboard walks, common substitutions like "@" for "a", dictionary words) make a password much easier to guess than its length alone suggests.
