What to run
Open Password Strength and paste a copy locally. It stays in the browser.
How to read the result
The score is a heuristic in the page: length, classes, and common patterns.
It is not a breach check.
A high score does not mean the password is unused elsewhere.
The value never leaves the browser.
What to open next
Open Password Generator if the score is weak. It stays in the browser.
Open Hash Generator only if a system asked for a digest, which is a different job. It stays in the browser.
