## What is "Cracked" Minecraft?
Cracked or non-premium Minecraft refers to copies of the game that are not purchased through the official Mojang/Microsoft store. These clients cannot authenticate with Mojang's servers, which means they are blocked from joining servers that have online mode enabled.
## How Online Mode Works
Minecraft servers have a setting called in the file:
- (default) — The server verifies each player's account with Mojang. Only legitimate, paid accounts can join
- — The server skips Mojang authentication. Anyone can join, including cracked clients
## How to Enable Cracked Client Access
- Go to your game panel and select your server
- Navigate to the **Files** tab
- Open **server.properties**
- Find the line
- Change it to
- Save the file and restart your server
## Important Security Warnings
Disabling online mode comes with risks you should be aware of:
- **No identity verification** — Anyone can join using any username, including impersonating other players
- **UUID changes** — Player UUIDs are generated differently in offline mode. If you switch from online to offline mode, players may lose their inventory, ender chest contents, and progress
- **Vulnerability to griefing** — Without authentication, it is easier for bad actors to join and grief your server
- **Some plugins may break** — Plugins that rely on Mojang UUIDs (e.g., skin plugins, permission plugins) may not work correctly
## Recommended: Use an Auth Plugin
If you run your server in offline mode, we strongly recommend installing an authentication plugin to protect your players:
- **AuthMe** — Requires players to register and log in with a password. Works on Paper/Spigot servers
- **LibreLogin** — A modern alternative to AuthMe with better security features
These plugins prevent username impersonation by requiring a password on each login.
## Crossplay Note
If you are using **GeyserMC** for Java + Bedrock crossplay, the setting works differently. Refer to our Crossplay Guide (/kb/article/setting-up-crossplay-java-bedrock-with-geysermc) for the correct configuration.
## Our Policy
AgilaHost does not restrict you from running your server in offline mode. However, we do not provide support for issues caused by cracked clients or offline mode configurations. Use at your own discretion.
