title: Can I ask user to re-authenticate Apple ID login
body: <p>I would like to create a kiosk-mode with limited functionality for my app, which would require a user password to be entered to unlock the kiosk-mode and get back to poweruser-mode.  In doing so, I would prefer to not create my own password system, but I would rather prefer to have the user authenticate using their existing Apple-ID.  They will already be logged into their Apple-ID, but is there a way for me to request they log in again? </p>
  
  <p>Maybe I'm just being lazy.   </p>
