How to Allow Cracked Clients on Your Minecraft Server (Disable Online Mode)
⚠ Important Warning
Disabling online-mode allows players without a premium Minecraft account to join. This reduces security and allows name spoofing unless you install proper protection plugins.
By default, Minecraft servers verify accounts with Mojang/Microsoft. This setting is called online-mode. To allow cracked (non-premium) clients, you must set:
online-mode=false
Step 1 — Open Properties in the Panel
In your server panel, go to:
Configuration → Properties
Step 2 — Search for online-mode
Use the search bar and type online-mode. You will see a toggle with the current value set to true.
Step 3 — Toggle to False and Save
- Switch the toggle OFF (so it becomes false)
- Click Save
- Restart your server
Changes only apply after a full server restart.
Recommended Security (Very Important)
When running in offline mode, anyone can join with any username. To protect your server:
- Install AuthMe Reloaded (for Spigot/Paper)
- Force players to register with a password
- Enable IP limits
- Use anti-bot protection if public
⚡ Performance Note
Disabling online-mode does not improve performance. It only disables Mojang authentication checks.
Done! Players Can Now Join
After restart, cracked clients can connect normally using:
IP:PORT
