OpSec Mod protects your privacy when you play on multiplayer servers. It stops servers from tracking your account, checking your keyboard presses, or seeing what other mods you have installed. This mod gives you tools to block unwanted data collection and keeps your game safe from sneaky server tricks. You can even switch between different Minecraft accounts easily right from the menu.
