Please note the following points:
・For security reasons, the 6-digit two-step verification code is updated every 30 seconds. Therefore, it is necessary to enter the code within the validity period for two-factor authentication.
・ There is a circular timer next to the 6-digit code, so please check it while typing.
・ If you enter the code when the number has just been updated, you can enter it more easily.
・ Close the two-factor authentication app completely and restart it.
・ It is possible that the time of the timer rarely changes.
However, it rarely happens that the time slightly gets changed automatically.
