Hello, I can ask about this. However, if you are able to log into the forums, you should be able to link an email to your account, allowing you to have a login method, otherwise, you might be able to set up login credentials through CS.

Hello, please create a new thread for a new issue.

In regards to your login not working, did you set a password as well? Have you tried to see if it would allow you to login through the Naruto Online website?
