Google announced a new security feature for Gmail that should help users ward off hackers and scammers from accessing their email accounts.
This new feature is an extrapolation of their existing remote sign out and information about recent account activity feature that was introduced back in 2008. This information is still at the bottom of your inbox, but very few bother to look at the details.
Now, if Gmail detects something unusual going on with your account, the new system will alert you by posting a warning message saying, "Warning: We believe your account was last accessed from…" along with the geographic region of the suspicious IP address. For example, if you usually sign into your account in India, and suddenly someone has logged into it from Poland, this would set off an alert.
By clicking on the "Details" link next to the message, you can see the last account activity window that you’re used to, along with the most recent access points.
