Google has provided users with tools right within the Gmail inbox that can help keep your account secured. Here’s how it works:
Log into your Gmail account using a desktop browser. Scroll down to the bottom of your inbox and locate a link called “Details”. When you click on it, a pop-up window will appear, and it will show you a detailed list of the last ten times you – or anyone else –has accessed your account. It will also show you how and where it was viewed. You’ll know if the inbox was opened using an email app, browser, smartphone app and the IP address through which it was accessed.
