Facebook's Trusted Contacts feature lets you specify friends who can participate in the password-recovery process.
There’s no one ideal way for a website to let you recover a lost
password — one which will always let you get back in without inordinate
hassle, but which will never allow an imposter to compromise your
account. So sites typically provide multiple recovery methods. And after
a period of testing, Facebook is formally announcing a new one today
called Trusted Contacts.
Trusted Contacts is an updated version of an existing feature called
Trusted Friends, which lets you specify friends on Facebook who can help you get back into your account. Using the service’s
security settings,
you name three to five friends — the kind, Facebook says, who you’d
entrust with a copy of your house key. Then, if you ever get shut out of
your account, you can contact all the friends you chose. Facebook will
give each of them a unique code to relay to you; if you enter all the
codes, you can restore access to your account.
As Facebook’s blog post on the news notes, this approach isn’t
absolutely free of security concerns: someone could conceivably figure
out who your Trusted Contacts are, impersonate you and initiate the
recovery process. For that reason, the company encourages members who
take advantage of the feature to contact their pals in person or on the
phone rather than by e-mail or chat.
