Facebook says that users can now sign up for two-factor authentication as it introduces two new functionalities. The Facebook two-factor authentication tool essentially facilitates additional layers of security for online accounts using apps like Google Duo
and Google Authenticator
, thus strengthening the security on the site. The latest update which is now mostly available to most users was quietly rolled out by Facebook since last month. Hitherto, you could only sign up for the feature with a phone number or through Facebook's own code initiator that lives within the app itself. With the new two-factor authentication feature update, it has become much easier for the users to enable two-factor authentication by creating a streamlined setup flow that guides users through the entire process. The two-factor authentication is set at a considerable standard of security even if someone tries to get your password or it gets leaked as part of a hack, with the new provision no one can log in without physical access to your second-factor device. Scott Dickens, Product Manager at Facebook writes that two-factor authentication “is an industry best practice for providing additional account security.” The stipulated provision of two-factor authentication can be enabled by users when they log in to their Facebook account and go to the Settings menu and click on the Security option. Then by selecting the option to enable two-factor authentication, they can follow the setup to complete the process. Another Facebook-owned service Whatsapp
also has a form of two-factor authentication that can be enabled. It allows you to set a six-digit pin that you will need to enter if you register your number with WhatsApp again. This prevents further hacks when someone else is trying to register your phone number on another device. Though the security feature does provide significant protection, it has its own limits. Facebook users had reported that they were receiving SMS notifications from the social media website after signing up for the two-factor authentication security feature. Facebook responses it saying that it was a bug which was not meant to be sent.
