Security question
Hello, I have been using apple devices for many years and I have never had any problems until today. i bought a new iphone and need to transfer data from one to another. I switched from iphone 8 to iphone 12 without any problem. I reset the phone to factory settings and now I want to transfer data from iphone SE to iphone 8 but it doesn't allow me because I can't remember security issues. It says to me that I don't have enough data for that. Why can't I get new questions by email and confirm via mobile number like I did for the previous account used by my wife ...? And how to solve this problem? With respect in the hope of a quick response and solution.
iPhone SE, iOS 13
