Autologin
by DRAEYEX
Autologin is a Fabric client mod that sends a saved login command to a server when the player joins, so the password prompt is skipped.
What it does
Autologin sends a saved login command for each server after the client connects, using a password the player stored earlier. The mod only automates that login command; it does not change gameplay, chat or server content. Passwords are kept in encrypted storage on the client, and a Show/Hide toggle controls whether the field is visible.
The mod works with the vanilla Edit Server screen, where a password field is added to each server entry. Players who run several servers with different authentication plugins can store a separate password for each one. The command is sent only to servers whose authentication plugin requests it, so other servers are not affected.
Autologin is released for Fabric 1.21.11 only, with 1.0.1 as the latest file dated 2026-07-24. It is installed on the player's side alone, so servers need nothing. The mod is released under All rights reserved and is not open source.
Key features
Automatic login command
After connecting, the client sends the saved login command when the server's authentication plugin asks for it.
Password field on server entries
The vanilla Edit Server screen gains a password field, so each server keeps its own stored password.
Encrypted password storage
Stored passwords are encrypted on the client rather than saved as plain text in the configuration.
Show or hide password
A toggle on the password field controls whether the stored value is shown on screen.

Use cases
Multi-server play
A player who joins several authentication servers can keep a different password for each entry and log in without typing it every time.
Who it’s for: Players who join servers that use a login command, such as those running an authentication plugin, and who want to stop typing the password at every join.
How it compares
AutoAuthme is a client-side Fabric mod for 26.2 under the MIT License and is not open source, so it targets a much later release than Autologin. Simpler Auth is server-side only and open source under the MIT License for 1.16.5 – 1.19, so it runs on the server instead of the client. PassEncryptor is also client-side only, open source under the MIT License and built for 1.21.11, the same version as Autologin.
