Share 'Am I doing this right? No password asked when switching people?'

I'm testing out Glubble before bringing it up to the attention of the rest of the family. I started out making the kids and I can easily switch to their account. Afterward, I can just as easily switch back to MY account! Isn't it supposed to ask for the Family password when you switch back? Or is there another way kids are supposed to log into the system?
