The two-factor authentication that enables users to protect their accounts and keep them safe , Facebook has brought about changes in the 2FA steps. The new update prevents the need to use a phone number making it easier for the users.

“We previously required a phone number in order to set up two-factor authentication, to help prevent account lock-outs,” Facebook Product Manager Scott Dickens wrote in a blog post. “Now that we have redesigned the feature to make the process easier to use third-party authentication apps like Google Authenticator and Duo Security on both desktop and mobile, we are no longer making the phone number mandatory.”

This means that , it will now also accept apps like Duo Security and Google Authenticator. The company also says the setup process has been refined, resulting in a more simple, guided experience when enabling 2FA. This update culminated as a result of a bug that had been reported that caused non-security-related SMS notifications to be sent to users’ phones. Facebook uses 362-65 as its authentication number and this number was used to send SMS to people giving them their Facebook notification without their consent. Replies to these texts wound up being posted to users’ Facebook profiles.

“This was not an intentional decision; this was a bug,” Facebook’s chief security officer Alex Stamos said at the time. “The last thing we want is for people to avoid helpful security features because they fear they will receive unrelated notifications.”

Well you’ll still be able to use your phone number for code delivery, of course, it’s just that now you have a few more options beyond that.
