The error you have experienced is usually related to login attempts using a different login method than the one you used to create the account. For example, if the account was created via Facebook login, attempting to use Google login to access it instead will trigger the error.

The primary solution to such is simple: utilizing the login method you have originally used to create the account.

Should there be an issue with that, an alternative method to access your account is via resetting your password using this link: https://id.kinguin.net/resetting/request. By doing such, even if originally you did not use e-mail and password to log in to Kinguin, you will be able to establish a password to log in from now on.

When it comes to connecting your Kinguin account with various apps, including alternative login methods, our team is constantly expanding such capabilities. You can access settings for such in your Account tab on the Kinguin dashboard. To avoid the error reappearing in the future, you can link the accounts from there while being logged into Kinguin.
