Introduction to Cracked Minecraft Servers
Allowing cracked versions on your Minecraft server enables players without official Minecraft accounts to join and play. However, this comes with security risks that can be mitigated with the right plugins.
Step 1: Stop the Server
To begin, you need to stop your Minecraft server. In the Console, click on the Stop button and 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
In the side menu, click on Files. At the root, find the server.properties file and click on it to open.
Step 3: Modify online-mode
Look for the line: online-mode=true. Replace it with online-mode=false. Click on Save. ⚠️ Before you flip this. With online-mode=false Mojang no longer verifies accounts, so anyone can connect under any username, an admin's included. Player data is keyed by UUID and offline-mode UUIDs are generated from the username, so switching modes on an existing world can orphan inventories, homes, permissions and economy balances. Skins and capes also stop working, which the SkinsRestorer step below fixes. On a public offline-mode server an authentication plugin is not optional.
Step 4: Restart the Server
Go back to the Console and click on Start. Check the logs for the following lines:
[Server] Starting Minecraft server...
[Server] Online mode: false
✅ Done! Your server now accepts cracked players.
Secure Your Cracked Server
When online-mode=false, anyone can connect with any username. A malicious player could connect with an admin's username and gain their permissions or impersonate other players.
The Solution: Authentication Plugin
Install a plugin that requests a password upon login. Recommended plugins include:
| Plugin | Description |
|---|---|
| AuthMe Reloaded | The most popular, very comprehensive |
| Login Security | Simple and lightweight |
| nLogin | Modern, good performance |

- 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
