I don't know what you mean by "non-monetary assets", but here is a relevant passage from the Terms of Service:

Account Security
Keep your account safe! - No one except you should ever know your password or have access to your account. It is forbidden to share passwords or accounts, grant someone else access to your account or access another knight's account. You are responsible for the security of your account data and are likewise responsible for everything that happens on your account, including rule violations of any sort. You can find more information on how to protect your account in this article about account security.
