appleTV keeps asking for appleID, password and authentication code circularly

MatsA got it right - solved my issue. Enter password; do NOT hit "submit;" request a code using another device (phone for me...settings; tap your name; password&security; Get Verification Code link at the bottom); attach the generated code to the end of your password; hit "submit." Done. This worked perfectly but ticked me off a bit: how would anyone know to do that without searching for and finding an answer on the Internet. I am thankful to those who posted here and hope this helps another frustrated Apple customer. (Why would the code not work in the provided boxes and have to go on the password line? Crazy!)

Late to the party but for anyone who might be struggling with this....

I went into the settings area. Logged out of my iTunes account. Logged back in. It asked for the verification code; I entered it and the ATV accepted it.

Then went to movies, everything worked normally.

Fixed: go into your apple device under security settings. On appletv once you enter your pword follow the pword (don't hit go) have your device sent the 6 digit code to you. Then enter those 6 digits to the end of your password.

So example:

Pword: ericisgreat

But add the 6 digits

So, ericisgreat345987

Exactly. With all due respect to those that have replied to me I am having the same problem. I have tried everything and adding a number to the end of the password field ( either I tunes out Apple ID) gets a very definite invalid ID or password? I have tried with two factor authentication off as well same result. There are two sign in's on the TV remember one for the ID and the other for the I tunes. Is there anything significant I have missed on this perhaps.

Good news I have after several weeks got it to work. There is really ONLY one way and I mean ONE way. Thanks for all the suggestions though . First like it or not you HAVE to have two factor authentication you don't have any choice. Two you have to reset your Apple TV from scratch . Three you have to set up manually. Sorry but this is the one and only way to do it. I don't like two factor authentication consider a normal TV, you want to change channels you have to go to the kitchen. And turn on your toaster to get permission, or maybe your refrigerator. Rediculous. Or you don't know whether you have to wear a tie or a long sleeve shirt or short sleeve one. if these were provided by Apple you would have to take them all with you as to change shirts you would have to ask permission from your tie or maybe your other shirt. In the old days, well you just wore them and I dont see the future of TV being that created by Apple. They could do better , better in thinking up a security solution. An Apple TV is not a portable device really it needs to be connected to a TV! So what's the point of all this? It took too long far too long to get this solution, and in the process I spend hours. No not the futur of TV a nightmare on TV!

There is no choice apparently two factor authentication is compulsory. And it seems a ploy by Apple to get you to buy more Apple products. After all without more than one you cannot authorise any device nor log on?

The fix is to generate a 6-digit code using your iPhone and enter it immediately after your password on the AppleTV.

In order to generate a code, go to the iPhone:

-Settings

-Touch the personalized box at the very top of the Settings menu. This is the one with your name and AppleID, iCloud... listed.

-Touch "Password & Security"

-Touch "Get Verification Code"

That is the code you enter right after the password on your AppleTV. Remember not to put a space or anything else between the password and new code.

Was told this is for all older gen AppleTV's, as they don't understand 2-step verification.

Hope this helps.

If you are using two factor authentification with your Apple ID and if you have a 2nd or 3rd generation Apple TV, then follow these steps:

Go to settings on your Apple TV

Click on iTunes Store

Go to Apple ID and sign out if you are signed in

If you are not signed in, click on add new Apple ID

Sign in with your Apple ID and press submit

Put password in but DONT HIT SUBMIT YET

enter verification code immediately after the last character of your password NO SPACE Between both password and code

If no verification code was generated then go to your iCloud on another device, go to password and security and tap on "get verification code" then use that code on your Apple TV after password

NOW you can hit submit

If it asks you to have iTunes save your password, hit "yes"

Now you should be able sign into the iTunes store

Definite answer from support at Apple: Sign into iTunes on your Apple TV, after you have typed in your password (which we did 35 times) type the verification code immediately after it. No space. You have 90 seconds after you get the code to insert. It is a one time verification and you won't need to do it again. You may need to do this for your iTunes account on desktop and iPad as well. I feel your pain! I hope this has helped!

I have been asking this on and on and overtime I try the verification code at the end of my password it simply says INVALID ID/Password. Although a lot of followers have been very helpful in suggesting various ways to do this so far I have never managed to get it to work. Overtime you turn on the TV I need a verification code before I watch something. Every new programme and/or pause invariably needs the password again and I am sorry I suspect that Apple have changed what happens and make it so that this occurs. There we have spend money on buying programs and we have to prove to Apple each and every time we want to play them that were are entitled to.

It is irritating. Its also not secure as there is a temptation to simplify the password to make re-typing it quicker. Not a good security practice.

Had the same problem on my gen 1 Apple TV. Finally paired Bluetooth keyboard, entered my password, got the code, quickly entered my password again with the code after it and it worked. I have a longish password and it was timing out due to how long it takes to use the apple remote to enter passwords.

Your only choice for the 2nd generation ATV may be to disable 2-factor authentication.

I had this same challenge tonight after purchasing a movie via iTunes. I kept trying to get into viewing it on my 3rd gen AppleTV. I finally got fed up and turned off 2FA and it worked successfully.

Agreed. Apple's implementation of 2FA has made my Apple TV device a brick. Steve Jobs must be turning over in his grave.

On Apple TV 2, under Airplay, Verification, there is an option to select Device Authentication. Turn this off and all will be well.
