I just came across what I feel is a good setting for most Facebook users. It allows you to get an email notification of anyone using your Facebook account from an unauthorized computer. I personally use a number of computers to update my Facebook status but, I still want to get notified every time something happens outside of my main computer (and hopefully I can register my laptop also).
You go to:
ACCOUNT > ACCOUNT SETTINGS > ACCOUNT SECURITY
click the CHANGE button
The setting is “Would you like to receive notifications for logins from new devices?
Then LOGOUT of FACEBOOK.
When you first log back in to FACEBOOK you will be asked to verify and name that device.
Give it a meaningful name and Voila.
I will be testing this to see how annoying the notifications are but, it looks good.
