How to allow cracked versions on your Minecraft server

Estimated Time: 2 minutes
Difficulty: Beginner ⭐
Compatible Servers: All Java Minecraft servers

📋 Introduction

By default, a Minecraft server checks that each player has an official Minecraft account (premium) before allowing them to connect. This verification is called online mode (online-mode).

By disabling this option, you allow players with non-premium (cracked) versions to join your server.

Why Allow Cracked Versions?

✅ Advantages ❌ Disadvantages
All your friends can play, even without an official account Reduced security (possible username spoofing)
More potential players Authentication plugins (AuthMe) become necessary
No Mojang verification Official skins do not display by default

⚙ Method 1: Using OuiPanel Settings (Recommended)

The simplest method is to use the startup settings in OuiPanel.

Step 1: Accessing the Settings

  1. Log in to OuiPanel
  2. Select your Minecraft server
  3. In the side menu, click on Configuration

Step 2: Modifying the Online Mode Setting

  1. Look for the "Online Mode" or "online-mode" setting

  1. Change the value:

    • true → Only premium accounts can connect
    • false → Everyone can connect (cracked allowed)

  2. Select false to allow cracked versions

Step 3: Restart the Server

  1. Go back to Console
  2. Click on Restart

✅ Done! Cracked players can now join your server.

📁 Method 2: Using the server.properties File

You can also directly modify the configuration file.

Step 1: Stop the Server

  1. In Console, click on Stop
  2. Wait for the server to completely stop

⚠ Important: Always modify server configuration files while the server is stopped to prevent your changes from being overwritten.

Step 2: Open server.properties

  1. In the side menu, click on File Manager
  2. At the root, find the server.properties file
  3. Click on it to openImage

Step 3: Modify online-mode

  1. Look for the line:
online-mode=true
  1. Replace with:
online-mode=false
  1. Click on Save

Step 4: Restart the Server

  1. Go back to Console
  2. Click on Start
  3. Check the logs:
[Server] Starting Minecraft server...
[Server] Online mode: false

✅ Done! Your server now accepts cracked players.

🔒 Secure Your Cracked Server

The Security Issue

When online-mode=false, anyone can connect with any username. A malicious player could:

  • Connect with an admin's username and gain their permissions
  • Impersonate other players

The Solution: Authentication Plugin

Install a plugin that requests a password upon login.

Recommended Plugins

Plugin Description Link
AuthMe Reloaded The most popular, very comprehensive SpigotMC
Login Security Simple and lightweight SpigotMC
nLogin Modern, good performance SpigotMC

Quick Installation of AuthMe

  1. Download AuthMe Reloaded on SpigotMC
  2. In OuiPanel → File Manager → plugins folder
  3. Upload the .jar file
  4. Restart the server

Basic commands for players:

  • /register <password> <password> - Create an account
  • /login <password> - Log in

Admin commands:

  • /authme reload - Reload the configuration
  • /authme register <username> <password> - Register a player
  • /authme unregister <username> - Delete an account

📖 Check the guide "Installing Plugins on Your Minecraft Server" for more details.

🎹 Bonus: Displaying Skins

In cracked mode, official skins do not display. To solve this issue:

SkinsRestorer Plugin

  1. Download SkinsRestorer: SpigotMC
  2. Install it in the plugins folder
  3. Restart the server

Commands for players:

  • /skin set <username> - Apply a premium player's skin
  • /skin url <url> - Apply a skin from a URL
  • /skin clear - Remove your skin

🔧 Troubleshooting

Cracked players still cannot connect

❌ Cause ✅ Solution
Server not restarted Completely restart the server
Incorrect file modified Ensure you modified server.properties at the root
Incorrect value Verify it is online-mode=false (without spaces)

Error "Failed to verify username"

This error appears when online-mode=true. Check that:

  1. The parameter is set to false
  2. The server was restarted after the modification

A player can connect with another player's username

This is the normal behavior in crack mode. Install AuthMe to secure your server (see section above).

BungeeCord / Velocity (Proxy)

If you are using a proxy (BungeeCord, Velocity), the configuration is different:

  1. Backend servers (Lobby, Survival, etc.): online-mode=false
  2. Proxy: Configure authentication at the proxy level

⚠ Also enable bungeecord: true in spigot.yml on the backend servers.

📝 Summary

QUICK METHOD (YesPanel):
1. Configuration → Online Mode → false
2. Restart the server

MANUAL METHOD (server.properties):
1. Stop the server
2. File manager → server.properties
3. Change: online-mode=true → online-mode=false
4. Save
5. Start the server

SECURITY (highly recommended):
1. Install AuthMe Reloaded
2. Players must /register and /login

BONUS:
‱ SkinsRestorer to display skins

⚠ Legal Warning

We encourage purchasing the official game on minecraft.net to support the developers.
