NeoAuth Mod (1.21.1, 1.20.1) – Fix Login Errors In-Game

NeoAuth Mod brings the features of the Auth Me mod to the NeoForge mod loader, letting you fix your game session without leaving Minecraft. It helps solve the common session validation error that can stop you from joining a server. Instead of restarting the game, you can simply re-validate your account from the main menu. This is a client-side mod, which means you can use it on any multiplayer server without needing the server owner to install anything.

Features:

• Fix your Minecraft session directly inside the game instead of restarting.
• Built to work specifically with the NeoForge mod loader.
• Works on any multiplayer server because it only needs to be installed on your client.
• Keeps almost all the features of the original Auth Me mod, but does not include offline authentication.
