You need to setup a user profile other than the default master profile. These settings can be found under "Profiles" on the Sub-menu when you highlight "System" on the Main Menu. Then set what you want to have access to with the channel and group manager, then give the profile a name and password. *You should first set a password for the Master user. As for the favorites, if you mean favorite channels from the channel list, you could just add that channel to the KODI favorites (Star Icon), or you could make a profile called Favorites and Add only the channels you want to see. If you mean an external Add-on channel, you can add this also to the Kodi Favorites. /kens
