WARNING: If your server is allowing cracked clients then that will allow people to steal people’s usernames, inventory and so on. To prevent this we recommend you to download an authenticating plugin such as AuthMe Reloaded.
A Cracked Client means someone is using a non-premium Minecraft account using a service such as Mineshaft. This means people do not need to buy Minecraft.
Changing to offline mode/allowing cracked clients:
Access your server's FTP.
Edit the server.properties file.
Set online-mode=true to online-mode=false
Save the file.
Restart your server
We provide limited support on cracked servers as we do not suggest running on due to the security risk involved.
