Facebook receives a staggering 600,000 logins from impostors seeking to access users’ accounts. Facebook is concerned about its users’ security as an impostor can access all the user’s information, and the real user can be denied access and effectively be locked out from their account if the impostor changes the password for the account. The social networking site has therefore revealed a “Trusted Friends” tool, whereby a user can nominate up to five friends to be sent login codes if they are locked out of their account following a hacker’s change of the password.
