  • The passcode is updated every 30 seconds.
    Please make sure to use the updated passcode from Google Authenticator.

  • The time may change in the middle of entering the passcode.
    When entering the passcode, please wait a little after starting the Google Authenticator and make sure to promptly enter the passcode after it changes.

  • While using Google Authenticator, the time on the device (smartphone, tablet, etc.) on which the application operates must be set correctly.
    If you are entering the correct passcode but cannot log in, make sure that the device’s time is correct.
    Also, when setting the time, it is recommended that you set your time to automatic.

Please enter the Passcode and then click on "Submit" button.
