Facebook app password without logging out?

[tc2010]

So my friends and family (yes I'm guilty too) are famous for getting hold of each others phones and posting stuff on their Facebook. What I am wondering is, is if it is possible to require a password to get on the Facebook app every time but still receive notifications like I were still signed in.

I use LockDown... but it's a Jailbreak app. I do believe there's non-Jailbreak apps that perform similar functions... just not for certain.
