Your Facebook account has a secret email address. It's best to keep the secret, of course, but you should know your Facebook upload address — to post just by email or share images and videos.
Should anybody gain knowledge of your secret Facebook email address and thus access to updating your wall and account, you can have a new random and newly secret address generated.
