## Description

Auth Autofill is a Chrome browser extension designed to streamline identity verification services in South Korea. It automatically completes fields such as name, mobile phone number, birth date, and preferred authentication methods for a variety of government and credit-related services, including Ministry of Public Administration portals, credit bureaus, and mobile carrier authentications.

The extension securely stores users' personal information locally within the browser, ensuring privacy with no data transmitted to external servers. It supports a broad range of services like government24, home tax, mobile certification by Korea Mobile Certification and Danal, and more. By minimizing repetitive data entry and navigating complex multi-step verification processes, Auth Autofill enhances convenience and user experience while complying with South Korean laws restricting resident registration number collection.
