Idmsa / business account? / MDM

idmsa- as I opened my iPhone I was asked to confirm that I would allow signing in with idmsa- so I impatiently taped on it- then thought why do I need this? I’m obviously not tech savvy…

then I read on about business account and managed accounts which I am very concerned about, I am not a managed account yet it seems that I may be getting tricked into this option illegally by my neighbor a hacker creep…. Why do I need idmsa? I better not be managed and if I am it would explain how this person knows so much and why so much fraud goes on with my online accounts . Please don’t bother saying this is being paranoid, it’s not paranoiawhen things are actually happening- big difference
