How to Allow Cracked Players to Join a Minecraft Java Server

There are two ways to allow cracked/offline-mode players to join your Minecraft Java server.

⚠️ Important: Disabling Online Mode removes Mojang/Microsoft account authentication. This means players can potentially join using another player's username. If you enable offline mode, it is strongly recommended to use an authentication plugin such as AuthMe.

Method 1 — Using the Options Menu

This is the easiest and recommended method if your server type supports the Online Mode option.

If you don't see this option, use Method 2 instead.

Steps

1. Stop your server.

2. Open your server Control Panel and go to the Console.

3. In the Control Panel sidebar, navigate to Minecraft Java category.

4. Click Options.

5. Find the Online Mode option.

   💡 Note: Your server must have been started at least once for this option to appear. If you've never started the server, start it once, then stop it.

6. Disable the Online Mode checkbox.

7. Click Save.

8. Restart your server.

After the restart, cracked/offline-mode players should be able to join your server.

Method 2 — Using server.properties

If the Online Mode option isn't available in the Control Panel, you can manually change it in the server.properties file.

Steps

1. Open your Control Panel.

2. Go to the Server Console.

3. Stop the server.

4. Open the File Manager.

5. Find and open the server.properties file.

6. Find the following line:

online-mode=true

7. Change it to:

online-mode=false

8. Save the file.

9. Restart your server.

Your server will now allow cracked/offline-mode players to connect.

⚠️ Important Security Notice

When online-mode is set to false, Minecraft no longer verifies players' accounts with Mojang/Microsoft.

This means someone could potentially join using another player's username.

For this reason, if you run an offline-mode server, we strongly recommend installing an authentication plugin such as AuthMe to require players to register and log in.

Which method should I use?

If the Online Mode option is available in your Control Panel, we recommend using Method 1. It's faster, easier, and avoids manually editing configuration files.

If the option isn't available, use Method 2 and edit server.properties manually.

That's it! Your server is now configured to allow cracked/offline-mode players.
