5．How to troubleshoot when the two-factor authentication code does not appear in the app or you cannot find it
5-1．Being asked to enter an authentication code even though you do not recall setting up two-factor authentication.
If you suspect that a third party may have accessed your account, please contact our support desk to have 2FA temporarily disabled. After logging in, please check your login history from the "Activity" section on the "Account" page.
If you find any login activity that you do not recognize, we strongly recommend changing your password.
5-2．The two-factor authentication code is not appearing in the authentication app.
Please check whether the login entry labeled ‘pafin / pafin Inc.’ is present in your authentication app.
We regret to inform you that we are unable to provide support for the operation or behavior of authentication apps. If the login entries within your authentication app were not carried over due to device loss or a device change, or if the entries were accidentally deleted within the app, these may be possible causes of the issue.
If you would like to have two-factor authentication disabled, please contact our support desk.
5-3．I don’t know the two‑factor authentication code.
・Check the authentication app on the device you are using (such as your smartphone or tablet).
・Check the recovery codes.
For security reasons, we may ask questions related to the information you have previously uploaded to cryptact to verify your identity before disabling 2FA.
However, if your paid plan is set to renew automatically, you will need to cancel the renewal yourself. Therefore, please log in after two‑factor authentication has been disabled.
