Where are other phones signed in with my Apple ID
My phone is always getting hacked
I believe it’s someone I know
how can I tell where else and when someone else is signed into my Apple ID?
Question marked as
Contact legal advice, local victims assistance organization, or police, as ongoing issues are usually either civil or criminal matters.
If you haven't already had the following guide or similar referenced, and have not already used Safety Check and the provided checklists, then start there: Personal Safety User Guide - Apple Support
There's a PDF of that guide available at the bottom of that same web page.
But if this is ongoing, and if you've already worked to secure your environment, and as you suspect you know the culprit, again, get legal assistance.
