2. If you cannot log in with 2-step verification

If you can’t log in with 2-step verification, try the methods below.
 

① Enter the latest passcode

Start the 2-step verification app (Google Authenticator) set on your smartphone and enter the “latest passcode” that will be updated in a certain period of time (30 seconds). Please note that old passcodes cannot be used.

② Enter the passcode after switching once

The passcode will change after a certain period of time during input. Therefore, when entering the passcode, wait for the passcode to switch once and then enter the updated passcode.

 
③ Check the automatic correction function of the clock

To use the 2-step verification app, the “time” of the device (smartphone/tablet) must be set correctly.

Please check if the automatic setting function of the terminal is turned on by yourself.

 

④ Two-step verification app for previous devices

If you change the model and the 2-step verification app remains on the previous device (smartphone / tablet), please try the passcode of the 2-step verification app.

 

If you still can’t log in after trying the above, cancel 2-step verification and reconfigure.
