About this page
This page describes the MyKey Platform, an authentication infrastructure provided by the Digital Agency for administrative services using My Number Card and the Public Personal Authentication Service (JPKI). It offers two approaches: PPID method and MyKey ID method. The PPID method has two types: Type ① API for face-to-face services supporting contactless card reading without PIN input, and Type ② API for various scenarios including non-face-to-face environments. Both enable secure authentication by issuing unique identifiers per service and linking them with My Number Cards to administrative systems.
