Sometimes you may like to step back and take stock of what you're doing online -- to this end, Google added "Account Activity," a new feature in Google Account, that shows stats for services like Google Latitude, Gmail, Google Search and more.
"If you sign up, each month we'll send you a link to a password-protected report with insights into your signed-in use of Google services," informs Google. From the Account Activity page, you can opt in for a monthly report that provides a "summary of your account activity across many Google products".
"Knowing more about your own account activity also can help you take steps to protect your Google Account. For example, if you notice sign-ins from countries where you haven't been or devices you've never owned, you can change your password immediately and sign up for the extra level of security provided by 2-step verification," Google explains.
For example, Google shows a list of locations and browsers detected when you've signed in. If you never use Opera, but the browser is included in Google's list, then it's likely that someone else found your password. The activity page also includes the number of emails you've sent and received, the number of Google searches and stats from Google Latitude, Picasa Web and YouTube.
