theres a random iphone connected to my appl ID
I went into my setting recently to just mess around in them and learn more about my phone and all the stuff it’s capable of doing, I obviously started by clicking on my the first thing which is my Apple ID account tab upon doing that I scrolled down only to realize that there was 4 devices that were linked to my account rather than the original three. My phone, my girls phone, and my iPad are the only devices that should have access to the account at all but I seen a device named iPhone and it was an iPhone 11 Pro Max which me and my spouse have never owned nor do I even know anyone with one, what’s weird is the phone number linked to the phone when I type it into the search bar in contacts is literally brings of 5 of my contacts and that said phone number is on all their Contact info cards I’ve never changed their numbers either so I need a explanation if possible of what the **** is going on, I’m also not able to sign outta my iCloud account in settings now please help someone, thank you
iPhone SE, iOS 17
