Two step / factor authentication is a good thing to access anything iCloud related. However.... I have two iPhones connected to my iCloud account, my own personal iPhone and a work iPhone. Whenever I am asked to enter a two step authentication code, Apple sends the code to my work iPhone. As I don't always have this phone with me, I would like the code to go to my personal iPhone. The Apple support pages direct you to login to appleid.apple.com but the only option here is to remove this iPhone from iCloud completely, which I don't want to do! Does anyone know how I can change the two step authentication from my work iPhoen to my personal iPhone without disabling iCloud completely? Thanks in advance.
