Facebook has unveiled new measures to keep members secure when they log into its site. One is a temporary password; another is letting people sign out of Facebook remotely. Finally, it will also now regularly prompt members to update their security information. “Our new features are aimed at protecting people who log in from devices they don’t own as well as helping people who lose access to an account get it back quickly,” Facebook spokesperson Simon Axten told TechNewsWorld. Facebook members must have first listed a mobile phone number in their account information.
