Parental control
If you wish to restrict certain content from displaying for a user, you need to set it in your Emby server. Emby for Kodi will import exactly what is displayed in the web client for that user. For more information: Emby Parental Control
If you set an access schedule in your server, Emby for Kodi will respect it. Keep in mind, if you select Native playback mode, the add-on will be unable to restrict playback.
