So, I have two computers and I use my smart phone's internet on those computers. Yahoo during a brief period actually locked me out of my account because "try logging in on a device i normally log in on", and I constantly get security alerts from google for logging into my gmail on my smart phone. For example, today I downloaded mozilla because of a I encountered when trying to download something off google drive, and then when I downloaded the file off mozilla my phone sent me another security alert.
So this begs the question: what data is analyzed by these corporate robots to determine what is "a new device"? Is there a simple command that will show all this information in windows?
