Separate Apple ID on additional iPhone
I currently have an iPhone XR set up with an Apple ID (of course). I just purchased an iPhone SE 2nd Generation for another family member in the same household. I'm sure (hoping, that is) that there is no way these phones are related so that when a new Apple ID is created for the new phone my Apple ID will be affected, right? I mean, just because I purchased the SE and had it mailed to me doesn't mean that creating the new phone's Apple ID will somehow screw up mine will it?
I know this is stupid, stupid, stupid, but I'm a handwringer when it comes to this stuff.
