I need to change my iCloud security questions
So I just got this new iPhone yesterday & I can’t activate my iMessage?? I figured if maybe I went to my phone’s iCloud settings I could fix it and properly “sign in”(?), but I made these security questions when I was like 14 and now I do not remember any of the answers. Point in case: I really need to change my security questions but I have NO clue how. Help!!
