SAN FRANCISCO – If you’re worried someone’s trying to hack into your Facebook account, now you can lock it up with a key.
On Thursday, the social media giant said it would let users link a hardware token to their accounts. When you log in from new browsers or geographic regions, you can plug the piece of hardware into your USB drive and give it a tap. That’s enough to convince Facebook you are who you say you are.
It’s a highly regarded, if not very common, form of two-factor authentication — security measures in which you add an extra layer of security to your logins beyond your password.
“We use similar technology to protect our internal assets here at Facebook,” said Brad Hill, a security engineer at Facebook. “We find it to be convenient and highly secure.”
The update makes Facebook one of the first major social media services to give users this option. It also comes at a time when savvy users are exploring their options for keeping hackers out of their accounts.
