You can configure your Minecraft server to allow cracked (non-premium) players to join. However, disabling online mode removes Mojang’s authentication system, meaning any player can join using any username, posing a security risk. Proceed with caution.
1. Log into the Pterodactyl panel and open your server
2. Head to the file manager
3. Open server.properties
4. Change online-mode=true to online-mode=false
5. Restart your server
