パスワード変更

What is パスワード変更?

パスワード変更 is a macOS utility included with JPKI client software for Japan’s Public Personal Authentication Service. It helps users change password settings associated with a My Number Card when using a compatible IC card reader on Mac. In typical use, the utility opens a password selection dialog, lets the user choose the relevant certificate or card function, and then accepts the old password and new password to complete the change. It is part of the broader JPKI desktop environment used for certificate-based identity tasks, notification features, and related card utilities. People usually encounter this app after installing the JPKI software package and opening the 公的個人認証サービス folder in Applications or Utilities.

Key features

• Change My Number Card public identity password settings on Mac
• Select the certificate or card function whose password you want to update
• Enter the current password and set a replacement password
• Work with the JPKI desktop tools used alongside an IC card reader

Safety overview

Status: Safe

This utility is part of Japan’s official JPKI client software and its access to a connected IC card reader is normal for its purpose. It is intended to update password information for My Number Card certificate functions, so use it only when you are actively managing your card credentials. Make sure you are following the official password rules and keep your new password private. If you remove the JPKI software, this password-change tool will no longer be available on your Mac.

Recommendation: Keep this utility if you use JPKI services, a My Number Card, or related certificate features on your Mac. If you no longer use those services and want to remove the full JPKI software package, you can remove it with the rest of that suite, but you may lose card-management features you still need later.
