login for 1.21.1
by wyskj
Login adds a registration and login system to NeoForge servers for 1.21.1, so players authenticate before they can play.
What it does
Before authentication, a player is placed in a restricted state where movement and interaction are blocked, which keeps unauthenticated players from affecting the world or taking part in mob-farm and environmental exploits. Once a player logs in, temporary states are restored correctly after login or logout, and the player is returned to the last saved location, including dimension and coordinate rotation. First-time players are sent to the default Overworld spawn point.
Login suits operators who prefer running their own authentication rather than relying on external login plugins. Timeouts, attempt limits and waiting locations are set in a generated configuration file, and a default configuration can be viewed before changes are made.
Login is server-side only, so joining players need no extra software on their end, though the server requires client-side dependencies to run. It is released under All rights reserved and is not open source. Files are published for NeoForge 1.21.1 only, with version 1.0.0 released on 2026-07-06.
Key features
Registration and login
A complete registration and login flow, with a prompt that appears when a player joins.

Built-in TPA requests
Players can send teleport requests to each other with TPA and TPAHere, without a separate utility mod.
Account commands
Commands cover the account-management tasks needed for registration and login on the server.
Configurable limits
Timeouts, attempt limits and waiting locations can be adjusted in the configuration file.

Who it’s for: Operators of NeoForge 1.21.1 servers who want login and teleport requests in one mod. Players need nothing installed on their clients.
How it compares
NullPass is server-side only, released under the MIT License and built for NeoForge 1.21.1, but it is not open source. Remove Blindness is also server-side only and open source under the MIT License, and it targets NeoForge 1.21.1. NoTimeOut runs with a required server side and optional client side under the Apache License 2.0, so clients may leave it out.
