To prevent your Facebook account from being hacked, enable and use two-factor authentication. This binding protection measure put in place by the network will prevent anyone from accessing your data.
The security of your Facebook account is essential in order to enjoy the social network with peace of mind. It is very easy to have your credentials stolen by a relative or an unscrupulous hacker. A moment of inattention, and here you are with unwanted publications on your wall – in the best case scenario – or even in the total inability to access your account, the identifiers having been modified. And impossible to reset your password, since the recovery email arrives on another mailbox than yours! To avoid this kind of inconvenience, Facebook has implemented a two-factor authentication system, a very simple and effective security feature that is added to your usual password. To access it, you will need to provide a second code, which you will receive by SMS or via an application, or press a security key from a compatible device. On top of that, you’ll receive an alert whenever someone tries to log in from a browser or mobile device that the platform doesn’t recognize. However, this function must be activated manually because the platform does not activate it automatically.
Three two-factor authentication options are available to you: via a code sent by text message, by an authenticator application or by a security key. The latter is a small device used to protect a program. Once connected to the device, it allows specific software to run or decrypt its contents. Access is therefore limited to only users with the appropriate key. We will not deal with this last option for two-factor authentication on Facebook because it is very little used – and represents a certain financial investment.

In this example, we will use Google Authenticator.
