About this project
What does AccProtector add?
🛡️ Server Account Protector
This mod is designed specifically for Minecraft servers to ensure maximum security. It completely prevents unauthorized users from logging in under someone else's username, protecting player accounts from being hijacked.
✨ Key Features
• Secure Authentication: When a player joins the server for the first time, a clean registration menu pops up, prompting them to create a password.
• Seamless Login: On every subsequent join, a secure login menu will appear to verify the account owner.
• Easy Password Management: Players can change their current password at any time using a simple in-game command: "/resetpassword", "/change_pass", "/reg"
⚙️ Admin GUI & Configuration
No more messy chat commands! Server administrators can now manage all security settings directly through an intuitive built-in Admin Panel GUI:
• Max Login Attempts — Easily configure how many times a player can enter a wrong password before being kicked.
• Require Registration — Toggle with a single click whether registration is strictly mandatory for everyone. When enabled, players can set their password using the "/reg" command.
• 5-Minute Auto-Login — Enable or disable the session timeout to let trusted players bypass password entry on reconnect.
