Nickname Changer is a client-side mod that lets you change your in-game username directly from the Minecraft title screen without restarting the game.
Features:
In-game UI: Adds a "Change Nick" button to the main menu. Auto-saving: Remembers and applies your custom nickname automatically on startup. Quick Reset: One-click button to restore your original account name at any time. Validation: Enforces standard Minecraft name rules (A-Z, 0-9, _, max 16 chars). Languages: Supports English and Russian. Why use it? This mod is specifically useful for LAN players who need unique names on the same network, content creators who want to hide their real username, and developers testing server plugins under different player names without needing multiple accounts.
Note: This modifies your local session name. It works perfectly in Singleplayer, LAN, and offline servers, but cannot be used to join premium (online-mode=true) servers.
