Phone: iPhone 3 or iPhone 3GS iOS: 6.1.6
I tried to login to App Store , iCloud and iTunes with an existing Apple ID, it shows the below alert:
I’ve done that multi factor login from my MacBook to iPad and vice versa. But on my iPhone it does not work. It doesn’t give me an option to type in the 6 digit verification code. What should I do? I don’t mind resetting it.
