You can use the Forgot Password flow. However, if you don't know what email address it was attached to Fandom can't generally help you, because they have no way of knowing it actually is you. Knowing your email addresss part is your own responsibility. You can always submit a contact form to see if they can help you; expect a reply in 1-3 business days.
