Supports Bukkit, Spigot, Paper, Purpur, Folia, BungeeCord, Waterfall, and Velocity — all in a single JAR. --- ## Features - Register and login system with `/register` and `/login` - Passwords hashed with **SHA-256 + random salt** per player — never stored in plaintext - Offline session cache — players don't need to re-login after briefly disconnecting - Full movement, chat, and command restrictions until authenticated - Blindness effect applied to unauthenticated players - Login timeout on proxy (auto-kick if not logged in within X seconds) - **Session sharing** — login once at the proxy, stays logged in across all backend servers - No external database required — uses a simple flat file (`players.dat`) --- ## Compatibility | Platform | Supported | |---|---| | Bukkit / Spigot | ✅ | | Paper / Purpur | ✅ | | Folia | ✅ | | BungeeCord / Waterfall | ✅ | | Velocity | ✅ | Minecraft version: **1.21.1+** --- ## Installation **Standalone (Paper/Spigot only, no proxy):** Drop `LoginMe.jar` into your server's `plugins/` folder and restart. **With proxy (BungeeCord / Velocity):** Drop `LoginMe.jar` into **both** the proxy `plugins/` folder and every backend server's `plugins/` folder. The proxy handles authentication and shares the session to backend servers automatically. --- ## Commands | Command | Description | |---|---| | `/login <password>` | Login to your account | | `/register <password> <confirm>` | Create an account | | `/reg <password> <confirm>` | Alias for `/register` | --- ## Configuration Located at `plugins/LoginMe/config.yml`: ```yaml prefix: "&7[&bLoginMe&7] " # How long to keep a session after a player disconnects # Supports: s (seconds), m (minutes), h (hours), d (days) offline-cache-duration: "5m" # Proxy only: kick player if not logged in within this time after joining login-timeout: "60s" messages: login-success: "&aLogin successful!" already-logged-in: "&cYou are already logged in!" not-registered: "&cYou are not registered! Use /register <password> <confirm>" login-usage: "&cUsage: /login <password>" wrong-password: "&cWrong password!" register-success: "&aRegister successful!" already-registered: "&cYou are already registered! Use /login <password>" register-usage: "&cUsage: /register <password> <confirm>" password-mismatch: "&cPasswords do not match!" please-login: "&ePlease login with /login <password>" please-register: "&ePlease register with /register <password> <confirm>" must-login-first: "&cYou must login first!" must-login-chat: "&cYou must login first to chat!" login-timeout: "&cLogin timeout! Please reconnect and login." titles: login-success: "&aLogin Successful!" login-success-subtitle: "&7Welcome back!" register-success: "&aRegister Successful!" register-success-subtitle: "&7Please login with /login <password>" ``` All messages support `&` color codes. --- ## Data Storage Player data is stored in `plugins/LoginMe/players.dat`. Each entry contains the player's UUID alongside a randomly generated salt and SHA-256 hash of their password. The file is human-readable but **should not be edited manually**.
