利用者クライアントソフト
利用者クライアントソフト is the Mac desktop utility for using Japan's public personal authentication certificates on a My Number Card.
What is 利用者クライアントソフト?
利用者クライアントソフト is a Mac utility for people who use Japan’s Public Personal Authentication Service with a My Number Card. It helps users work with the electronic certificates stored on the card when accessing supported e-government and online filing systems. On macOS, the app is used to check certificate details, confirm that the software is working with a card reader, change certificate passwords, and handle related certificate tasks such as status checks and revocation requests. It is part of the JPKI workflow rather than a general-purpose identity app, so users typically install it when a government or administrative online procedure specifically requires it. The software also includes update-related options and browser integration support for compatible web-based procedures.
Key features
- View the electronic certificates stored on a My Number Card.
- Check whether the client software is working correctly with your card reader setup.
- Change certificate passwords for supported JPKI functions.
- Open and inspect certificate files and certificate authority information.
- Submit certificate revocation-related requests through supported workflows.
- Adjust proxy settings for networks that require them.
- Check the installed version and update-related settings.

Safety overview
Status: Safe
This is legitimate government-related client software used for My Number Card certificate operations on macOS. Access to a compatible IC card reader, certificate data, network connections for supported online services, and related browser integration is normal for its purpose. Keep in mind that removing it can stop supported e-government sign-in, certificate viewing, password changes, or other card-based procedures from working on this Mac until the software is installed again.
Recommendation: Keep 利用者クライアントソフト if you use a My Number Card for online government procedures on this Mac. If you no longer use those services, you can remove it, but card-based certificate tasks and supported browser-assisted workflows may stop working until you reinstall it.
