This isn’t a particularly new feature, but very handy especially if you worry that your Facebook account might be compromised. If that’s the case however, you should go change your password (to something strong) before reading the rest of this article. I’ll wait.
Facebook’s login notification feature will send you an e-mail whenever your account is logged into from a new device (or a different browser on the same device).
To enable these notifications:
- Click the down arrow next to Home in the top-right corner and click Account Settings.
- In the left-hand navigation, click Security.
- Click Edit next to Login Notifications.
- Select the ways that you want to receive login notifications.
- Click Save Changes.
The next time you login, you’ll be prompted to enter a name for the device that you’re using. This name can be anything, it doesn’t have to be the computer’s network name.
If you click Save Device, you won’t be prompted to enter the device name the next time that you login from that device, but you also won’t receive a notification for that device. Obviously, clicking Don’t Save means that you will be prompted with this screen the next time that you login from that device and you will receive a notification.
If you don’t enter a name when prompted, the notification will indicate that the device is unknown and will provide the IP address and approximate IP Geolocation. Otherwise, the notification will also include the name that you provided.
On the Security Settings page you also have the ability to review your recognized devices and close sessions that are logged in from other devices.
