## About

## What it does
Password Strength Checker scores a password based on length, complexity, and common-password checks. Send a `password` string in the query, and get back a structured assessment with `score`, `max`, `level`, and a `checks` object that flags individual rules as pass or fail.

Use it when you need to evaluate passwords at signup, during password resets, or in admin tools that enforce account security policies. The `level` field returns one of `very_weak`, `weak`, `fair`, `strong`, or `very_strong`, so you can map the result directly into UI messages or acceptance logic. `score` and `max` give you a simple numeric grade, while `checks` lets you inspect which validation rules passed.

Password Strength Checker is a fit for login flows, customer onboarding, and internal security audits where you need a quick client-side or server-side password quality check without building your own scoring logic.
