    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.
    Depending on the version of Google Authenticator, the passcode may turn red or start to blink, which is a sign that the passcode is going to change soon.
