NeoLogin
by kmrvit
NeoLogin is a NeoForge login mod for servers that require players to register and authenticate before they can play, with passwords stored using PBKDF2 hashing.
What it does
Players register an account with a password and sign in each time they join. Passwords are hashed with PBKDF2, and the interface supports English and Russian. Account data can be kept in a local SQLite file, which works without setup, or in a remote MySQL database for networks with several servers. Passwords typed into chat commands are masked in the console log, and the mod includes a real-time monitor for server TPS and player ping shown in the action bar.
The mod runs on the server only, so players join without installing anything. A configuration migrator updates the structure of the config file when the mod is updated, which reduces broken settings and duplicate parameters. The latest NeoForge file is 1.1.2 for 1.21.1, published on 2026-09-23, and the mod is released under the MIT License. It is not open source. Builds target 1.21.1 only.

Use cases
Protecting an offline-mode server
Players must register and log in before they can take actions on the server, which keeps accounts separate.
Running several servers
A shared MySQL database lets accounts carry over between servers in the same network.
Who it’s for: Server owners who want password-based accounts on a NeoForge 1.21.1 server, and admins who need account tools such as password reset, forced password change and account removal.
