A few months back Google launched a feature in Gmail that notifies you when their servers automatically detect suspicious log in activity on your account. Since this has been effective in helping people identify improper access, They decided to extend it to all our Google Account users, not just Gmail. Starting this week, If they detect any suspicious log in on any of your Google Account products, they’ll display a notification on your Google Dashboard.
How does this work? Using the IP address you provide to us, our automated system can determine your broad geographic location. If you log in using a remote IP address, our system will flag it for you. So if you normally log into your account from your home in California and then a few hours later your account is logged in from France, you’ll get a notice like the one above at the top of your Dashboard page - alerting you to the change and providing links for more details.
When you get this notice and if you think your account has been compromised, you can then change your password directly from the ‘more details’ pop-up window.[via]
Or, if you know it was legitimate access (e.g. you were traveling or your spouse who uses the same account was traveling), you can easily click "Dismiss" and remove the message.
