Here's one very good method to stay on top of your FaceBook account, and get immediately alerted via email and SMS text message (if you choose to) if someone accesses your account. Setting this up is quick & easy, just follow the tutorial below.
Next, look down by "account security" and click the "change" link. (Fig-2)
Fig-3 is where the bulk of your 'work' is.
You can choose to turn on or off notifications that you'll receive instantly after a new computer is detected and added to your Facebook account. If you turn it on you'll automatically get the notifications to your stored Facebook email address. If you choose "Off", you'll only see the information when you visit this page at any time in the future to view the activity.
In addition, you can have a notice sent to your cell phone via a text message as well. Personally, I like to have them both turned on.
Beneath that you'll see a list of all computers that have been detected, given a name, and added to your account.
Followed by the activity of the very most recent computer, which should be the one you're currently using.
If you use multiple computers, of multiple people share the same Facebook account, and they happen to be connected at the same time as you, you'll see their activity below your activity.
Once you have setup your Facebook account to keep track of computers that connect to your account, the next time you (or anyone else) logs into the account, they'll be greeted by the above screen (Fig4), asking you (or them) to give a Name to the computer you're connecting with. Once you type in a computer name (it can be anything you want), click the continue button. If you checked the box below where you enter your name, you'll never be asked to re-enter a name for this computer, or be greeted by this screen when you login. You'll log in as usual, and go right to your usual Facebook account page. There are a couple of exceptions, as noted at the bottom of this article.
Fig-5 shows an example of the email notice you'll be sent anytime a new computer has been added to your Facebook account. Notice how it gives you detailed information on the computer that's been added, such as the Name it was stored as, it's general location, it's IP address (blurred out in the example) and the time it was added.
If this is not you, or anyone you know, now is the time to click the link highlighted in light-purple above.
Finally, if you also enabled SMS Text notices, Fig-6 shows an example of the text message you'll receive at the same time as the email notification. This is very handy in case you happen to be out and about, you'll be immediately able to protect your Facebook account.
And that's all there is to it!
Here are some important tips:
Of course this isn't a 100% guarantee your account won't be hackable. Rogue Facebook applications and Facebook games can always still reek havoc if they want to, and there are some other ways, but this is a very nice step in keeping yourself a bit safer. So have at it!
