## Description

PwdHash is a robust Chrome extension designed to boost your online security by automatically generating per-site passwords. By simply prefixing your password with @@ or pressing F2 before entering it, PwdHash creates unique, hashed passwords tailored for each website or subdomain, preventing password reuse and reducing vulnerability.

This extension also protects you by blocking JavaScript from reading your passwords as you type, ensuring enhanced privacy. Passwords generated stay consistent across subdomains (e.g., a.example.com and b.example.com), supporting seamless user experiences across related sites. You can also generate hashed passwords online at [pwdhash.com](https://www.pwdhash.com/). For developers and contributors, the project is open source and available on [GitHub](https://github.com/pwdhash/pwdhash-webextension).
