Well - I'm sorry to say so - but it's actually your own mistake for not printing out / writing down the removal code when you've registered the OTP. SE was even kind enough to send notification emails to all OTP users recently to remind them of that as well so you're really only one to blame. What would be the purpose of loging in without OTP anyway - that would defeat the whole security purpose of it in a first place. I know it's pain to not be able to access game / account but SE did warn you.
