There are Facebook Friends and then there are TRUSTED Facebook Friends
As part of a new security measure, Facebook will let you designate three to five friends who can access your account in case you are unable to do so. It's the Facebook equivalent of giving a neighbor the key to your house, the company says. The program is in test phase right now but should roll out to everyone in coming weeks. Choose carefully.
The best thing is, this has no chance whatsoever of being a complete disaster for teenagers.
