🛡️ BetterAuth

BetterAuth is a client-side Minecraft mod designed to keep your account secure by masking sensitive authentication commands and providing a seamless auto-login manager for your favorite servers.


✨ Features

  • 💬 Chat & Command Masking: Commands like /login, /register, or /changepassword are automatically hidden in your chat and replaced with asterisks (***). This prevents accidental leaks of your passwords while streaming, recording, or taking screenshots!
  • 🚫 Safe Command Suggestions: Stops your sensitive passwords from showing up in the vanilla command suggestion popup.
  • ⚡ Auto-Login Manager: Securely save your credentials per server IP and username. When you join the server, the mod will automatically authenticate you—no more typing!
  • ⚙️ In-Game Configuration GUI: Everything can be configured directly in-game! Press the designated Keybind (configurable in Minecraft Controls) to open the BetterAuth menu.

    • Toggle masking, auto-login, and auto-saving on the fly.
    • Manage saved servers, view passwords, or delete entries.
    • Add custom commands to mask for specific servers.
  • 🌍 Localization: Fully translated into English, Ukrainian, Russian, and Kazakh.
