QLogin
by ZeroQing_
QLogin is a server-side login system for Fabric, Forge and NeoForge that holds unauthenticated players until they register or log in.
What it does
Before a player signs in, QLogin blocks movement, chat, interactions and commands, so an unregistered account cannot act on the server. Players use register, login, logout and changepassword to manage their account, and admins use reload, unregister, resetpassword and info to maintain it. A login timeout kicks players who take too long, and failed attempts can lead to an IP ban.
The mod stores accounts in SQLite and hashes passwords with SHA-256 and a salt. Messages are colored and a countdown appears in the action bar while a player waits to log in. Because only the server runs it, players join without installing anything. The mod is open source under the MIT License and is published for 1.7.2 – 26.2. Builds for Paper, Spigot, Bukkit, Purpur and Folia are also listed. The Fabric build needs Fabric API, which the author notes as a requirement for the Drop JAR variant.
Key features
Login gate
Unauthenticated players cannot move, chat, interact with the world or run commands until they sign in.
Account commands
Register, login, logout and changepassword cover the player side, with tab completion for the admin commands.
Timeout and IP ban
Players who stay unauthenticated too long are kicked, and repeated failed attempts can trigger an IP ban.
Hashed password storage
Accounts live in SQLite, and passwords are stored as SHA-256 hashes with a salt rather than in plain text.
