Your child must have input your email address through his/her player account and had the address verified specifically for this purpose before the 'forgot password' function will work. Please note that parents cannot change a player password through their parent account. To reset the password, begin by entering the username on the Returning Player login page, without entering any password, and then click the 'OK' button.
