Two-factor authentication with one Apple device
I have a new MBP, but no other Apple products. How do I use two factor authentication without another Apple product? At present I have to use the "Didn't get verification code?" button to get a code to my Android phone.
When I go to System Preferences and select iCloud, it asks me for a security code. But I've never received a security code. How do I get one?
