"Forcing passcode change on personal iPhone: Why is Apple forcing me to change my passcode now? It is my phone and I should be able to use whatever passcode I want for as long as I want. It belongs to me and not to Apple, if they want to pay me full purchase price for it then they can force whatever policies they want on the phone. I will buy a different phone if this is not changed."

Provide a Screenshot or Photo:
If you are getting a demand, then it is a scam. On the other hand, you might have you set one up again, but not mandatorily to reset it to be different than the original passcode. because you reset it or restored it form being locked.
So, reply with a screenshot, or a photo of what you are seeing. IMPORTANT: Block out any personal information(i.e. time and names) whatsoever, by covering it with red-colored rectangles and such through use of the Photos app.
