About
Estimates strength from length and character classes. It is a heuristic score, not a cracking simulation.
How to use
Type a password to see an estimate from very weak to strong.
What this tool does
Gives a local strength estimate so you can spot short or overly simple passwords.
Safety and privacy
Input stays in the browser. Still avoid testing real production passwords on a public screen.
Limits
No leak-database lookup and no claim against targeted guessing. It is a structural hint only.
FAQ
Is the password I type uploaded?
No.
Does a strong score mean it is safe?
No. Reuse, leaks, and how the site hashes still matter.
How is the score computed?
Mainly length and character classes. It does not search leak databases.
