According to my Google account access history, a new device (Samsung Galaxy S 4) was added to my Google account about 1 week ago. Google shows that the SGS4 accessed my account 4 times the same day - no other access since. The IP address Google shows for that device matches the IP address of my home internet. This is all very strange because:
I'm concerned about this because I've seen strange Google-related app/game charges on two of my credit cards dated yesterday, including one card that is not linked to my Google account at all. Both charges are pending, so the credit card companies won't do anything yet.
One other piece of info that might just be a strange coincidence: We have a family member visiting who does have a Galaxy S 4 and has been using our wifi. I've never used that device, but our guest has been using it for ~ a month at our home. Is it possible that Google somehow linked this device to my account accidentally for one day and one day only, even though it's been used other days? FWIW, it only shows on my Google account on not my wife's account.
- We do not own a Samsung device of any sort and have never owned an SGS4.
- I have had 2-factor authentication enabled on my account for years.
- I was home at the time, and my phone (which I use to get the 2-factor codes) was with me during the times my account was accessed.
