myshkin Toggling airplane mode on lockscreen would require pin/password, currently exactly that is possible from the quick settings panel (on the lockscreen) with 1 extra swipe (given airplane mode is in the default 4 top quick settings).
I understand the request, but i doubt GOS will allocate resources to this given it is already possible relatively easily (see above). I think the only chance of seeing that request fullfilled would be if aosp implemented it.
