Using Cracked (Non-Premium) Minecraft with Your Server
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 servers, which means they are blocked from joining servers that have online mode enabled.
How Online Mode Works
Minecraft servers have a setting called online-mode in the server.properties file:
online-mode=true(default) — The server verifies each player account with Mojang. Only legitimate, paid accounts can joinonline-mode=false— The server skips Mojang authentication. Anyone can join, including cracked clients
How to Enable Offline Mode
- Go to the Files tab in your panel
- Open server.properties
- Find the line
online-mode=true - Change it to
online-mode=false - Save the file and restart your server
Risks of Offline Mode
- 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, anyone can join with any username, including impersonating other players
- Some plugins may break — Plugins that rely on Mojang UUIDs (e.g., skin plugins, permission plugins) may not work correctly
- Anti-cheat limitations — Many anti-cheat plugins require online mode to function properly
Recommended: Install an Authentication Plugin
If you run in offline mode, install an authentication plugin to prevent username impersonation:
- LibreLogin — A modern login plugin with good security features (recommended)
- AuthMe — A widely-used alternative (development is slower)
These plugins require a password on each login, preventing username spoofing.
Crossplay Note
If you are using GeyserMC for Java + Bedrock crossplay, the online-mode setting works differently. Refer to our Crossplay Guide for the correct configuration.
