Friends phone has my passwords
I signed out of my iPhone XR running 16.5.1, my friend then signed onto my phone using her Apple ID. She doesn’t recall signing out on her phone before signing onto to mine. She then signed out of my phone and I later deleted her access (I cannot remember exactly how I did this) because I was getting her text messages. Now my phone is completely free from anything regarding her or her activities; however, on her phone she gets my logins and passwords for certain apps. How do I get my passwords not to be entered into her phone?
