Project overview
# Leather Auth Bridge ## Overview **Leather Auth Bridge** is a lightweight authentication plugin for Bukkit/Paper servers that enables seamless login for Leather Client players while maintaining full compatibility with vanilla authentication systems. --- ## What It Does The plugin provides two authentication paths: * **Leather Client users** — Authenticate automatically on join using their Leather session token * **Vanilla players** — Use traditional `/register` and `/login` commands Both work independently without interfering with each other. --- ## Why You Need It If you want to support Leather Client on your server, this plugin unlocks the full experience. Without it, Leather Client players have to manually authenticate like everyone else. With it, they get a seamless join experience while vanilla players continue using normal auth commands. --- ## Key Features * Dual authentication system (Leather Client + vanilla) * Configurable security settings * Session management commands * Offline mode support for LAN servers * Lightweight with minimal performance impact * Works with Paper, Spigot, and Bukkit --- ## Installation & Setup 1. Download `leather-auth-bridge.jar` 2. Drop it in `/plugins` folder 3. Restart server (config auto-generates) 4. Edit `/plugins/LeatherAuth/config.yml` and set a random secret 5. Run `/leather reload` --- ## Requirements * **Server:** Paper, Spigot, or Bukkit (1.19+) * **Java:** 17 or higher * **Leather Client:** v1.0.0+ (on player side) --- ## Configuration ```yaml # LeatherAuth config.yml secret: CHANGE_THIS_TO_A_LONG_RANDOM_STRING allow-vanilla: true kick-message: "Authentication failed. Please use Leather Client or /login." offline-mode: false ``` Change the `secret` to a long random string (32+ characters) — keep it secure. --- ## Admin Commands * `/leather reload` — Reload config without restart * `/leather status` — View active sessions * `/leather revoke ` — Revoke a player's session Requires `leather.admin` permission. --- ## Troubleshooting * **Players kicked on join?** Secret mismatch between server config and client settings * **Plugin won't load?** Ensure you're running Paper or Spigot * **Auto-login failing?** Verify player is using Leather Client v1.0.0+ --- ## Support Join the Leather Client Discord: https://discord.gg/bktX9vMqF3
