If you don’t want your children to be able to access certain add-ons within Kodi, you’ll probably want to enable parental controls to curb their viewing access.

Here is the top 3 methods of full parental control within kodi

1. Universal Parental Control

 

Universal Parental Control is built to work with videos played from your Kodi library and ALL addons. Addon developers do not need to change anything and Universal PC works even if metadata is disabled. Highly configurable: Set your PIN, set your watershed time, exclude addons if required, exclude modes if required.

2. Locking

If you want to make a source more private, you can use lockcodes or passwords to protect that source. The easiest way to accomplish this in Kodi, is using the GUI dialogs. First, enable the Master Lock in Settings/System/Master lock. After enabling the Master Lock, a Set Lock button will pop up in the Context Menu allowing you to set a lock on specific sources. Kodi will ask for the master lock codeand then give you the opportunity to set a unique Password on that specific share. To Remove the Lock you need to remember the Master Lock code.

Locking a source means you only give it protection in Kodi. Outside Kodi the source is still available and only protected, or not protected at all, by the Operating System. In the same way, if someone has access to manually edit the sources.xml he or she can remove or change the settings for the locked source. So, don’t feel too safe when you protect a source in Kodi.
 

3. XBMC Parental Controls

 
In XBMC, go to Programs -> Parental Controls. The first time you will need to choose a code. Once you are in, you can select the video addons you wish to protect and the ratings you will allow. At that point, you can browse your video addons and it will block restricted content. Restricted content will be placed under a sub-menu that you need to enter your code to access.
