Somewhere in the future…
Until then, you can think of tons of simple ways to restrict access with widgets available at the moment. For example, in one of my projects there are four buttons acting like a pin input. Here is little screen cast: https://www.dropbox.com/s/6i4tdus9wivg75l/IMG_2327.TRIM.MOV?dl=0
Just in case someone finds it useful, here are the code excerpts:

І буває так, що ця дівчинка вимикає всю електрику в хаті.
