appleTV keeps asking for appleID, password and authentication code circularly

after updating my iPhone I was asked to use the double authentication code, I had no idea of what kind of nightmare this is. I spent hours going from a device to another checking passwords and authentication codes. The last one is the Apple TV, after this stupid innovation my appleTV keeps asking for my AppleID, password and authentication code, and than goes back to the request for the appleID. Basically my AppleTV is useless. how can I eliminate the stupid authentication code, that makes all my devices basically inaccessible?
