Auto Login & Auto Register
by Itamio
Auto Login & Auto Register fills in login and registration prompts on a server by sending a saved or generated password when the chat asks for one.
What it does
The mod watches incoming server messages for login and registration prompts, matched against configurable text patterns. When a prompt is detected, it sends the password stored for that server and username combination, or a newly generated one for registration. Passwords are kept in a plain text file in the server:username:password format, and a delay setting controls how many seconds pass before the login attempt is sent.
Players who join several servers that each use a login command can set up separate patterns and command formats for each one. Manual commands cover the cases where automatic detection fails or is disabled: one command forces an immediate login with the saved password, and another forces a registration with a new generated password. Auto Login & Auto Register is published for Fabric, Forge and NeoForge, and only the client needs it, so servers need nothing installed. Files cover 6 release versions, 1.8.9 – 26.1.2, and the mod is released under All rights reserved, so it is not open source.
Key features
Automatic login detection
Login prompts in the chat are recognized by text patterns, and the saved password is sent once the prompt appears.
Automatic registration
Registration prompts trigger a new randomly generated password, with its length and the context in which it applies both configurable.
Per-server password storage
Passwords are saved for each server and username pair, so one account on several servers keeps separate credentials.
Manual commands
Login and register commands run the action directly, which helps when detection fails or is turned off.
Configurable patterns and delay
Login and register patterns, command formats and the seconds to wait before logging in can be adjusted for a specific server.
