can't log into apple tv

I have a first edition Apple TV. It doesn't seem to like the two factor authentication. I have tried putting in my password followed by the verification code that I receive on my phone, but to no avail. I am quite tech savvy, but this one has got me stumped. The instruction clearly states to "type your password followed by this code into the password field on your device". This clearly doesn't work. I am using the right password, since I am able to login to here, but some insane reason when I try to login following the above instruction it doesn't work, I keep getting "Your Apple ID or password is incorrect"... when neither were... getting a little frustrated... when all I want to do is Apple+.
