I enter my apple id and password, then I'm taken to 'Enter iCloud Security Code, enter the security code that you created when you set up iCloud.... ' etc. I enter it, incorrect, I enter another, incorrect, I enter the first one again and it's accepted. Every day, multiple times a day. I even went into the apple shop and the person had never seen it before.
It's really limiting what I can do.
