Facebook is likely concerned about the security of our data. The social media giant has just put in place a new option to allow us to identify ourselves using a security key. The procedure to follow to set it up is quite simple, but this tutorial will still explain all the steps to follow to set up this function.
Facebook has been offering a two-step identification system for a while to prevent us from losing access to our accounts.
It offered three different locking functions and it was thus possible to protect access to our account by relying on a text message, a code generator or even on recovery codes.
U2F lands on Facebook
Facebook wanted to go a little further and now offers a fourth layer of security: U2F security keys.
Contrary to what one might think, this standard does not really fall from the sky. It was indeed initiated by Google, NXP and Yubico in 2015. Since then, of course, a lot of water has flowed under the bridges and this standard was thus recognized by the FIDO alliance at the end of last year.
In fact, to function, this standard is based on a physical key, a key that must be connected to our computer as soon as we wish to access one of our protected accounts.
These accessories are not very expensive. They are indeed sold from around ten euros and they work with all services compatible with U2F. It will also not be necessary to buy a different key each time to secure our different accounts. The same key will indeed be able to manage several different profiles.
Several services have taken the plunge. This is particularly the case of Gmail and Dropbox, but also of DashLane. Facebook had not yet implemented it. Not before today anyway. The service has indeed deployed the function a little earlier in the day.
To take advantage of it, you will have to start by buying a compatible key and waiting to receive it.

How to activate U2F on Facebook?
When it's done, all you have to do is paste yourself on your computer and go to Facebook. After having clicked on the small arrow located in the upper right corner, you will have to go to the “Settings” option and then go to the section dedicated to “Security”. Pretty simple, right?
Certainly, but it is not over yet. Facebook will then show you a list of all the security settings associated with your account. To activate identification with the security key, you will need to click on the “Modify” link in the option entitled “Connection approvals”.
Several options will then appear on the screen. You will need to activate two-factor authentication and then click on the “Add a key” link in the section devoted to security keys. The service will then ask you to plug in your key and all you have to do is comply to activate it and associate it with your account.
Not everything is perfect, however, and the big problem with U2F is that it doesn't work with all browsers. To avoid unpleasant surprises, it will therefore be essential to activate a second authentication method, such as text messages.
This way, if you lose your key, you will still be able to access your account.
