Auto login mod
by kirbodevv
Auto login mod lets a player log in to a server with a short command, so the full password does not have to be typed at each join.
What it does
The mod was created because typing a password every time a player joins a server is inconvenient, especially on a Steam Deck. Auto login mod stores the account password and sends the login command automatically, so a single shortcut replaces the typing. The word login is appended to the message before it is sent in-game.
Passwords are kept in a Secure Storage area and encrypted, and the server password can be replaced in the configuration file. The file is alm.json, and edits take effect after the game is restarted, since configuration is not reloaded while the game runs. A plain text password is not written to the Minecraft directory where other people could read it.
Auto login mod is a Fabric client mod for 1.21.8. It is client-side only, so servers run without it and players alone need to install it. The license is CC0 1.0 Universal and the code is open source, with public source code and an issue tracker.

How it compares
Hide Password is also a client-side only Fabric mod under the MIT License, with files for 1.21.11 – 26.3, and its code is open source. OurEconomy is client-side only too, but it uses All rights reserved, is not open source, and covers 1.21.1 – 1.21.11. Custom Command Shortcuts is also client-side only under the MIT License, with files for 1.21.8 – 1.21.10, so its version range overlaps with this mod.
