In recent time, Facebook users have been battling with different malwares and hacks. A lot of people have experienced account hijack and stolen passwords. Some guys on my friend-list have had their accounts hacked with the perpetrator posting pornography and other illicit contents.

The worst is that a hacker might go extreme and completely change your password, as well as remove or change important information you will need to recover the account.

This can lead to total loss of account with your reputation also at stake.
So What Are Trusted Contacts?
Trusted Contacts are contacts on your Facebook friend-list that you can trust with your account security in the case of any issue with the account.

When these Trusted Contacts are added to your account, Facebook can reach out to them and request they help you with recovery of your account. These contacts would be sent a special security code via a URL and you can then call them to get the security code which you will use to recover your password.

I see this idea of Trusted Contacts as a form of adding Next of Kin to your Facebook account. For this reason, I would advice you to only add your spouse, family, friends or any other trusted persons to the list.
