SuperAuth

Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.

by SAGUMEDREAM · on Modrinth

A simple mod that helps you allow players to access Minecraft servers using Yggdrasil or the Mojang API when online mode is enabled

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.21–1.21.4Newest
Minecraft 1.20.4
Minecraft 1.20–1.20.1

⬇ Download for 1.21–1.21.4 ⬇ Download for 1.20.4 ⬇ Download for 1.20–1.20.1

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.

Don’t you want to lose some players when online verification is turned on? Or is setting the server offline causing Minecraft server security issues? Then this simple mod will allow your players to use other Yggdrasil verification servers or Mojang official online account verification, the account data will be distinguished, but offline mode players will never be allowed to enter the server!

By the way: When Mojang's Minecraft verification server is suddenly blocked in your region, this mod will allow players to enter your server based on their previous access to your Minecraft server and using Mojang's official account (this will cause some security issues, This can be turned on and off in settings)

Command: /superauth *

Determining whether to enable this feature can be changed through config/superauth.yml .
