Apple

So recently I bought a second hand iPhone 11.

It was completely reset when I bought it, everything setup perfectly, I can enable Find my iPhone and use all other features just fine. However, this guy seemed shady, and I'm concerned that he may have left find my iPhone enabled and then reset the phone, allowing him to track me after I set it up with my own information.

This probably is just a stupid worry, but I need some sort of reassurance or something so I know that isn't or could be the case.

Is it possible for this iPhone to have "find-my" enabled on two separate accounts? or is that just not possible, thank you.
