[LON] How can I find the linking method I used for my Lord of Nazarick account?

If your account is linked, in the Account Center you will see whether the Crunchyroll/social account is linked or not (Title Screen > Account).

If you are not sure what account you used to link your account, here are some tips:

You may check if the game is using your Apple ID by following the steps below:

1. Choose Apple menu  > System Settings (or System Preferences).
2. Click your name (or Apple ID) > Password & Security.
3. Click on Sign in with Apple to see the apps

To find out if the game is linked to your Google you can do the following:

1. Go to your Google Account Settings.
2. Click on Security in the menu on the left.
3. Scroll to Connected Third-Party Applications and Services.
4. Click See All Connections.

The steps can help you identify what account you have used for binding and to make sure you are logging in with the right method.
