Password for settings and to keep people from allowing apps to run when blocked with lockdown. (ex: installed on an employee's work PC).
Adding password for settings is a good suggestion. We definitely will consider this to add as a new feature.
Currently what you can do is to set the trusted account. Remove administators from "Others"->"Manager User Rights", and add your user id as the trusted users. As long as the user id or group is not in the trusted list, the user will automatically set to lockdown mode, and it will not allow any untrusted app to run. Untrusted user also can't change the settings (e.g. they can't switch to interactive mode, or modify the settings).
