After my ios 16.5 update a strange number has appeared as a trusted device
After my ios 16.5 update a strange number has appeared as a trusted device. The phone won't let me remove it. I changed my apple ID password but if this other number is still a trusted device and can receive verification codes does that mean that changing my ID password was pointless?
My own iphone number doesn't appear as a trusted device. How do I restore that?
iPhone 8, iOS 16
