In its security page Facebook wrote,” Finally, our newest advanced security feature, Login Approvals, is now available to everyone who uses Facebook. This is a two factor authentication system that we first announced last month.

According to the survey findings, parent supervision of online activity were absent in case of the children below the age of 10.

The survey even observed that about one million children have faced harassement, threats, or were subjected to cyber-bullying on the site during the past year.

In a blog post, Consumer Reports technology editor Jeffrey Fox wrote, "The fact that so many other Facebook users are still in the dark about the controls is troubling."

The feature will be an upgrade of a famous ‘Safe Browsing feature,’ that is an application containing a list of malicious sites that has been prepared by the technology giant to prevent its users from downloading malware-affected files from the net.

Though the ‘Safe Browsing feature’ has been around for more than two years, there are not many takers for it, except Google, which is using the system. The new malware alert feature is also based somewhat on the same pattern.

How does it work?
