Although you cannot make a discord account truly private, you can prevent users from adding your child or communicating with your child without their consent. Here are the settings we recommend:
Safe Direct Messaging: Keep me safe - this setting will prevent users from sending any media that Discord deems inappropriate from being seen.
Server Privacy Defaults:
- Allow direct messages from server members: Off - this prevents members of servers from sending direct messages to your Discord account
- Allow access to NSFW servers on iOS: Off - Note this does not apply to Desktop or Android devices
Who can add you as a friend:
- Everyone: Off
- Friends of friends: Off
- Server Members: Off
