About this project

What does Simple Login add?

Description

Simple Login is a lightweight and secure authentication plugin/mod designed for Minecraft servers, supporting versions 1.17–26.x. It provides a login and registration system where players must register using /register <password> <password> and log in using /login <password> before interacting with the server. Until authentication is completed, players are restricted from moving, interacting with their inventory, breaking or placing blocks, and performing other gameplay actions, ensuring protection against unauthorized access.

The plugin uses SQLite for data storage, with passwords hashed using BCrypt for secure account handling. An automatic update checker is included to notify server owners about new releases.
