Minimal Password Strength Checker

About

Minimal Password Strength Checker is a lightweight Chrome extension that evaluates password strength in real time and displays clear strength levels. The extension helps users understand how strong a password is based on length, character variety, and resistance to common or predictable patterns.

All password analysis is performed locally inside the browser. The extension does not send passwords to any server, does not store input data, and does not require any special permissions. It runs only when the popup is opened.
