Why does Facebook not ask for my password on iPhone anymore?

I have recently synced my Facebook with my iPhone and now I no longer need to use my password to log in, how can I change this so I have to sign in with my password again?

U check keep me logged in so it save the password try to delete all saved history from your browser then it must ask u for the pass now

I'm not exactly sure with an iPhone, but I just log 0ff fb each time after use, and when I go back through my phone it make me enter my password every time. Before when I wasn't logging 0ff, I could go 0n without entering anything, which I didn't like for privacy reasons.

Until you log off facebook via your phone… You will always be logged in and that is why it is not asking for your password.

VICTORIA: Click on the gear icon. Then click remove login info.
