Gmail added a new security feature today to alert users of suspicious activity that may indicate unauthorized access. Gmail already has a feature that lists IP addresses the count is open at, but the information is at the bottom of the page and Google found that most users don’t know it’s there. Now Google will use a banner right up front to alert users proactively of strange activity.
The warning will show a brief description of the activity and link to a list of current and recent sessions identified by IP and geographic location. Google says the warning will only be triggered if the system considers the account to be at risk. For example, if you usually log in from a certain geographic area, then a log in occurs from outside that area, the alert would be triggered. The interface also allows users to change their password if they believe their account is indeed compromised.
We always like to see better security options for users, but it will be interesting to see if Google gets a lot of false positives. Keep an eye out and let us know if you get this warning and what caused it.
