Today on my Facebook I saw a new (to me at least) feature to access your account if you lose access somehow.
The process is simple. You add 3 to 5 friends as trusted friends. Then if you lose access to your account, Facebook will give each of those friends a piece of a security code. The you can then contact those friends and gather the code to access your account.
This image is from the walk through where Facebook explains it in their own words:
The only benefit I see is that you now have a sort of trump card to always have a way back into your account. An attacker can hack into your account but you will always be able to utilize your friends to get back in. But what does this solve that a simple texted/emailed access code (two factor authentication) to you, the account owner, doesn't? I suppose it turns it into 3 to 5 factor authentication but is that ever necessary.
Especially at the cost of having to contact 5 different people and gather codes to log in and possibly do so over an insecure medium.
Is there really a benefit or is this security theater?
