When an authentication code screen appears after entering your credentials (For Administration Login users only)

Additional verification is required when an authentication code input screen appears after entering your User ID and password. Please follow the steps below:


1. We will send an email containing the verification code to the email address registered with your User ID.
Note: If you do not receive the email, please check the following:
・Check your spam/junk folder.
・Make sure you are not blocking emails from noreply@netlearning.co.jp.

2. Enter the verification code in the authentication screen and click “Verify.”

Note 1: The verification code is valid for 5 minutes. If it expires, click “Resend code” to request a new one.
Note 2: Once a new code is issued, all previous codes will become invalid.

If authentication fails, please check the following:
・Make sure the code has not expired.
・Ensure that you are entering the latest-issued code.
・Check that there are no unnecessary spaces or symbols in the input.
・Verify that similar-looking characters such as O (letter) and 0 (number), I, l, and 1 are not confused.

Note: If the authentication fails 5 consecutive times, you will be temporarily unable to log in. Please leave some time before you try again.

* The system cannot complete authentication if no email address is registered. Please contact your administrator to register your email address.

3. Once authentication is complete, you will be redirected to the post-log-in screen.

If you still cannot log-in after following all the above steps, your service may use a specified log-in page. Please confirm the log-in URL and try logging in again from the proper page.
If the log-in URL is correct but the issue persists, please contact us through the inquiry form. When doing so, be sure to select “General inquiries (Password confirmation, how to log-in, etc.)” in the “Inquiry Content” field.
