Parental Controls

Hi,

I would like to setup parental controls on OSMC on my Pi 3 - I don’t want my kids to accidentally watch anything they shouldn’t. Has anyone else done this, what is the best way to go about it?

Thanks in advance!

Your question is explained in the Kodi Wiki. Have a look at http://kodi.wiki. This should be your first port of call for Kodi related questions. OSMC really has no control of such functions.

You should consider using profiles.
