I created a apple id for my child to use on family share. I am trying to get him logged into a device but it says invalid id. When I do get it entered it wants to send a verification code to his id but I don't know where or how to log in to get it
I can't figure out how to log my childs appleID onto this device. When I enter it sends verification code but I don't know where to go get the code at his iCloud.com it will not let me enter. it says" I can only add the iCloud.com address that is already on file in your account?
iPad mini, iOS 12
