Facebook has announced plans to roll out a new security feature for accounts, dubbed Trusted Contacts. Under the scheme, an account owner will be able to pick three to five people to whom they can give special PINs. Should the owner have trouble getting into their account, three PIN holders will be able to help them log back in. It's not clear how quickly Trusted Contacts will become available to Facebook users.
Social networks, primarily Twitter, have come under scrutiny for the threat of account hijacks. Last week the Associated Press
' Twitter feed was hijacked, and a subsequent post about explosions at the White House
caused the Dow Jones to plunge until the AP
could assure people that the post was fake. A series of high-profile Twitter hijacks have taken place in recent months.
