Security breach
My boyfriend is entering my phone and sees every chat on viber, whatsapp, instagram, messenger and he said that he only hacked the icloud and he can see everything on my phone. However this is not my biggest concern. My iphone has not told me that there is unrecognized device or a notification that there is unauthorized entrance, If he can enter all this apps, he can enters the apps from my bank account where my money is.
I have changed my password several times, two factor authenticator is on, and I have logged out from every app and changed the password however he manages to get in my phone again.
I need immediate help with this since this is security breach.
