iCloud often asks for a 4 digit security code
When I was installing Sierra, one of the steps was suppose to text me a 4 digit security code for iCloud. Well I've been waiting for hours now, and never got a text. Anytime I go to iCloud, it seems like a 6 digit code is provided and I enter it. What the heck is the 4 digit code used for, and how do I get it re-texted to me if I need it? Thanks!!
