Resetting iPhone of a deceased person

Hi There

Im sorry to hear that your father passed away

You can reset the iPhone using a mac or pc, here’s a guide on how to: https://support.apple.com/en-nz/HT204306

But if your father had an Apple ID signed in on the iPhone, when you reset the iPhone, the iPhone will become activation locked. Meaning that the Apple ID password would need to be entered to continue setup

I hoped this helped
