How to keep your Facebook account safe
Facebook has some tools that aim to make its users feel more secure. Among them are two-factor authentication, receiving alerts from unrecognized logins or choosing a trusted friend to contact the platform if you lose access.

So, decide if you want to receive the alert through Facebook notifications, by messaging on Messenger or via registered email. To confirm your decision, you will need to enter your password.
Choose friends to unlock your account
Also available in the Extras Security section of the Security and Login page of Facebook, the feature allows you to choose between three and five friends to ask for help if you are unable to access your account.
