What is the OPGuard plugin?

OPGuard is a security plugin designed to protect Minecraft servers from operator (OP) access abuse. This plugin helps prevent attacks such as:

  • OP hijacking (taking over OP access)
  • Command injection
  • Illegal OP granting
  • Permission exploitation With proper configuration, OPGuard can become your server's main line of defense.

Installation​

1. Make sure the OPGuard plugin is already installed on the server​

To make sure, run the following command in the console

opguard

2. Set the OpGuard password​

To access Operator, a password is required to become an Operator, so to set the password do as follows

opguard password <password>

Run the command in the console to create a password,
If successful, the log "OpGuard (Okay)" will show up in the console

3. Using OpGuard​

The way to make a Server Operator with the password you've created is with the command:

opguard op <playerName> <password>

Example

opguard op admin1 abcdf123

Tips​

  • Use a strong password (uppercase, lowercase, numbers, symbols).
  • Don't use the same password as your Mojang/Microsoft account.
  • Change the password periodically.
  • Restrict access to the server console to trusted admins only.
  • Integrate notifications to Discord/Telegram if available.
