Points to note regarding the use of electronic certificates for resident registry cards

Please be careful not to let others know the password you set. It is very dangerous to share your password with others without permission, as they may impersonate you and perform application procedures that you do not understand. If you are concerned that your password may have been known to someone else, we recommend that you change your password immediately.

You can change your password in the following ways:
　

1. When changing from a computer

A Basic Resident Registration Card (Registered Resident Registration Card), user client software, and an IC card reader/writer are required. For instructions on how to change your password, please see the "Changing your password" page in "How to use the user client software" below.
　

• Windows users

Please see the page "Changing your password (Windows users)" (external link).

• Macintosh ( Mckintosh ) If you use

Please see the page "Changing your password (Macintosh users)" (external link).

2. When changing at the city hall, Hirao branch office, or Wakabadai branch office

You can change your password at the Citizen's Division on the 1st floor of City Hall, Hirao branch office, or Wakabadai branch office. In that case, please bring your Resident Registration Card with you and complete the procedures at the Citizens Division on the 1st floor of City Hall. If your Resident Registration Card does not have a photo attached, please bring an official document with your photo on it, such as a driver's license.
　

Also, as with the password for your electronic certificate, please do not lend your Resident Registration Card to anyone or tell them your password without permission.

If you enter the wrong password five times in a row, your card will be locked and you will no longer be able to use it. In that case, please bring your Resident Registration Card with you and complete the unlocking procedures at the Citizens' Division on the 1st floor of City Hall, Hirao Branch Office, or Wakabadai Branch Office. If your Resident Registration Card does not have a photo attached, please bring an official document with your photo on it, such as a driver's license.
　

The validity period of the electronic certificate is 3 years from the date of issue. The "validity expiration date" is written on the "copy of the electronic certificate" issued by the Citizen's Division at the time of issuance, so please keep it in a safe place.
Renewal (new issuance) of electronic certificates for Resident Registration Cards has ended. If you need an electronic certificate, please obtain a My Number Card.

Note: This is different from the expiration date of the resident registration card (written on the front of the card).

In addition to when the validity period of an electronic certificate expires, it will also automatically become invalid if there is a change in the information on the electronic certificate, such as a change of address due to moving, a change of name due to marriage, etc. . Additionally, if your Basic Resident Register card is changed, your electronic certificate will also become invalid.

The latest notices and user terms are posted on the "Public Individual Authentication Portal Site" (external link), so please check it regularly. You can also ``confirm the validity of your electronic certificate'' from the ``online counter'' on the site, so please check if necessary.
