Precautions regarding the PIN code of My Number Card

From here, we will introduce the points to note regarding the PIN code and what to do if you forget it. Make sure to set the PIN to "unforgettable" and "not guessed by a third party".

How to check your PIN

Since the security code is set for security measures, it cannot be confirmed later. However, depending on the municipality, when setting a PIN, it seems that there are cases where the password etc. is entered in the "copy (PIN entry slip)" and handed over. First, let's check the copy you received when you received it.

If you cannot find a copy and "I have a password that I can think of, but I am not confident", use the "JPKI User Software" app. After installing "JPKI User Software", open the app and tap "My Certificate". Select the digital certificate you want to check, and the password entry screen will be displayed on the next screen. Enter the password you can think of here, and if no error occurs, the password you entered was correct.

However, if you make a mistake 5 times here, the password will be locked, so be careful. If you try it once or twice and it doesn't work, consider initializing your password.

If I forget my PIN, can I reset it? What is the procedure in that case?

The password / PIN cannot be changed to a new one without entering the current number. If you forget it completely, you need to go to the municipal office where your resident card is registered and go through the procedure to reset it from the beginning.

Need to change regularly?

Although it has no expiration date and can be used continuously, it is important to change it regularly considering the possibility of information leakage.

The password / PIN itself has no expiration date, but the signature password for the digital certificate for signature automatically expires when the address or name is changed. When you move, be sure to change the address of your Individual Number Card along with the procedure for moving in. Therefore, it is a good idea to change your password when you move.

If you remember your current password / password, you can change it not only from the municipal office where you received the password, but also from your computer, smartphone, or Mynaportal AP.

Is it true that if you make a mistake, it will be locked?

If you enter the wrong password in succession, the card function will be locked. Please be careful because the signature password will be locked 5 times and the 4-digit PIN will be locked if you enter it incorrectly 3 times in a row.

If the security code is locked, you must go to the municipal office, reset it, and reset it from the beginning, just as you did when you forgot your security code.
