You want to enable the Whitelist on your server and manage it? It's straightforward!
Requirement
- You must be OP on your server to access /whitelist commands.
Enable Whitelist
To enable whitelist, you need to check a line in your server.properties. You can use the panel or access the FTP of your Minecraft server for that.
Check that the following parameter is present: white-list=true
If the white-list parameter is set on false, then the whitelist is disabled. Replace false by true.
Then restart your server from the panel so the modification will be applied.

To manage your whitelist, you have at your disposal a few commands for the panel or the game (only for OPs).

Enable whitelist.whitelist off

Add a player to whitelist.whitelist list
Display the list of players allowed to join the server.whitelist remove NICKNAME
