Facebook two factor authentication now supports apps like Authy, Google Authenticator
Facebook two factor authentication now supports third-party apps like Authy, Google Authenticator. Prior to this news, the social network relied entirely on SMS based authentication for your account’s security.
So, why is this a big deal? Think about it, you are traveling, or are in an area where there is no mobile service. You have access to the internet though, and wish to use it on your laptop. When you try to login to Facebook, you will be asked for a code which has been sent to you via a text message. When there is no mobile network signal, you won’t be able to access Facebook at all. The same scenario applies to lost or stolen mobile phones. You could get a replacement SIM card with the same number, but by then the thief may have had access to your Facebook account too.
That is why Facebook two factor authentication support for other apps is a blessing. You see, unlike SMS based codes, you don’t need a mobile network to get the authorization codes. You don’t even an internet connection for that matter. The apps work offline, and you don’t have to wait for a few seconds or minutes to get the codes. Another advantage to using some of these apps is that they work on multiple devices, so even if one of your phones power down due to low battery, you can use another device to get the code. This is a much more efficient, and secure way, and you don’t need a phone number for Facebook.
Quite frankly, we don’t know why it took Facebook this long to imply this method. Most other websites including Gmail, Outlook, and even Twitter have been supporting third party apps for 2-factor authentication.
How to setup Facebook two factor authentication using Authy or Google Authenticator or other apps?
Just download the authentication app which you want to use on your mobile phone. Open the app, and go to https://facebook.com/settings and click on the tab which says
“Security and Login”.
Under the “Two-Factor Authentication” options, you can select “Edit” button for the “Use two-factor authentication”. This will start a Wizard which will guide you through the process of adding the authenticator app to secure your Facebook account. You just have to verify the change in the settings by re-entering the password, choosing the app authenticator option, and using your mobile app to scan the QR code displayed on your computer’s screen. Once you do that, you can see a login code in the app, enter it in the Wizard’s window, to complete the process.
It may be a wise idea to start using similar security measures for your Email and other Social accounts too, if you haven’t done that already.
