I was not familiar with the MFA. In order to add an company account on the MFA on my iphone, I removed the school account on MFA on my iphone. Now I want to add my school account on the MFA again. So I registered on the website "https://aka.ms/mfasetup";. After I entered my school email and password, it showed that it sent notification to MFA on my iphone. But I can not find the notification. So I tried to add the school account on the MFA on my iphone, but it requires QR or some password, which I cannot find. Could you please help me with it? Thanks!
