Protect your Facebook account with 2-step verification (double authentication)
O Facebook is always thinking about the safety of its users in all social networks it operates. At the Whatsapp, for example, it is already possible to activate the unlocking of the application through the fingerprint to iPhone and smartphones Android.
In their main network, to make it practically impossible, the user can use the two-factor authentication system (also called two-step verification, depending on the application).
In addition to entering the traditional password to login, you must also use a special code sent to your smartphone via SMS or a specific application to do so.
This adds an extra layer of security when logging in, making hacking or malicious people much more difficult, since knowing just the password is not enough to access other people's accounts.
How to authenticate two factors on Facebook?
To do this, click on the down arrow next to the question mark in the upper left corner of the menu; press on "Settings" and "Security and login".
Then, scroll the scroll bar until you find the option ?Use two strong authentication?. click in "To edit" as in the image below.
From this moment on, just follow the instructions on the screen and choose which authentication method you want. Finally, click "Activate" and your account is more secure.
Using SMS or Application?
If you choose the cell phone message, you will need to register a number or Facebook use what you put in your data previously.
The code itself will always be a 6-digit number. If you want to disable the SMS code and use a third party authentication application, just follow the steps described above and click "Remove number".
In the case of the third party application, there are some that you can sync with the Facebook and they show a number on your phone screen as soon as you activate it. Usually they stay for a period of time showing up and then they end up being changed, being the same system adopted in bank iTokens.
Is she infallible?
According to an article in Kapersky, the system is not infallible, but within what we currently have the best barrier we can have. Not only Facebook, but several other networks use it to increase user security.
?Two-step verification, at least, means that a cybercriminal will not only have to find his password, but also access the second factor, which is much more difficult to obtain and which would involve stealing a cell phone or compromising an email account. ?.
