UserLoginProxy
Java mod listed for Minecraft 1.12–1.19. Downloads from the MC Java Mods app on Android.
⬇ Download on ModrinthAutologin feature for UserLogin 2.12.1+ and NukeLogin 0.0.4+.
Here, the “main plugin” refers to the UserLogin or NukeLogin.
Suppose you have a proxy and three servers: lobby, survival and mini-games. The lobby server has the “main plugin” installed, and here (and only here!) players log in (or register) and teleport through portals to other servers.
Let’s imagine that some player, BratishkaErik, joined the server, authorized on lobby, and went to the survival portal. Then, he decided to go to the mini-games server, but he needed to go via the lobby server:
- Without autologin support: BratishkaErik must log in manually as if he were offline on
lobbythe whole time he was on thesurvivalserver. This can be annoying for some players. - With autologin support: BratishkaErik logged in automatically as if he were online on the
lobbythe whole time he was on thesurvivalserver. Player don't need to do anything and he can go straight to themini-gamesportal.
Note that in the second scenario ipCache setting from “main plugin” config is not respected.
How to install
Jar-files
- Download “main plugin” and put it into plugins folder of your auth server.
- Download UserLoginProxy and put it into plugins folder of your Velocity 3 or BungeeCord proxy (not auth server!).
Configuration
- For “main plugin”: enable
autologinsetting inconfig.yml:
bungeeCord:
# ...
autoLogin: true
- For this plugin: add backend server(s) (where “main plugin” is installed) to the
auth-serverslist inconfig.yml:
auth-servers:
- 'lobby'
- 'another_lobby'
Finally, restart servers. Now players will be logged in automatically when changing server to lobby or another_lobby.
