NAuth
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
NAuth authenticates usernames using a custom registration and login system revolving around dialogs, paired with optional logout sparkles so other players know where you have logged out.
This add-on is meant for offline servers.
Commands
Open NAuth Settings
/function nnms_auth:settings
All configurations and authentications are done through dialogs, which means there is no need to execute or invoke commands other than this one.
Change password
/trigger change_password
Unregisters the invoker and provides the prompt for registering again.
