"Used my apple ID by unknown device; Sep 17, 2023, 3:03PM.

I not know this device, then I decided change apple ID Password. I tried. But, i can not change my password.

i forgot answer of Security Questions. So, I can not Reset Security Questions.

I received this message: "Cannot Reset Security Questions

We don’t have sufficient information to reset your security questions."

Please guide me.
