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