Hi. I'm not tech savy at all but my sibling is. I live a few hours away but when she visits she uses my user name and password to get online on her phone. She seems to bring up things I have privately searched often. It's weird...because I know she's not a mind reader. What ways would this be possible for her to do this? Please advise. I'm married and I'd love to find out if she is doing this...and if she is...how can I find out and shut it down.
