App Store won't accept my password for logging in
Every time I try to download the new OS the app store asks for my password. After entering the correct iCloud account and password I get the message "An Apple ID verification code is required to sign in. Type your password followed by the verification code shown on your other devices." However there is only room for my password, and it then tells me it's incorrect. It seems like I'm very stuck!
