Minecraft plugin AuthMe

🔌 About AuthMeReloaded

AuthMeReloaded is a Minecraft plugin that enforces account authentication on servers. It prevents unauthenticated players from interacting with the world (placing blocks, moving, using inventory or commands) and provides features to secure offline-mode setups, manage session login, and integrate two-factor authentication and email recovery.

🎯 Purpose

The plugin's core purpose is to protect player accounts and server integrity by requiring a verified login for players before allowing normal gameplay. It is aimed at server operators who need authentication on offline-mode servers, or additional verification and session control on online-mode servers.

⚙️ Features

• Enforced login/registration flow that blocks actions for unauthenticated players.
• Session login to avoid repeated authentication on reconnect.
• Two-factor authentication (2FA) support.
• E-mail recovery and confirmation flows for account recovery.
• Multiple storage backends: SQLite, MySQL, MariaDB and PostgreSQL support for account data.
• Support for different password hashing schemes (SHA256, Argon2, Bcrypt, PBKDF2 and others) and compatibility with several external hash formats for migration.
• Built-in anti-bot protections and configurable login/registration timeouts.
• Premium bypass (allowing verified Mojang accounts to skip password prompts) with optional PacketEvents integration or proxy-backed verification.
• Graphical login/register dialogs on supported server platforms.
• Country whitelist/blacklist and username length checks.
• Native proxy-side modules for BungeeCord and Velocity for networked setups.

🧩 Who It Is For

• Operators of offline-mode / cracked servers who need account-level authentication.
• Servers that require explicit login/registration gating (small to large public servers).
• Networks using proxy software that want centralized authentication control via proxy modules.

🏗️ Example Use Cases

• An offline-mode SMP requires that every connecting player registers a password before interacting with the world.
• A network uses the proxy-side plugin to verify players at the proxy and forward authenticated UUIDs to backend servers.
• A server uses email recovery and 2FA to reduce account theft and allow players to recover passwords securely.

🔐 Permissions

⚙️ Installation

📥 Setup

• Download the appropriate official jar for your server platform and version.
• Place the jar file into your server plugins/ directory.
• Restart the server and check the server console to confirm AuthMe loaded.

The project provides dedicated builds for different server types and version ranges; pick the jar that matches your server platform and Minecraft version.

📦 Dependencies

• PacketEvents (optional) — required for some features such as premium bypass on direct connections and inventory protection when those features are enabled.

🧠 Technical Notes

• Official builds are provided for multiple targets (separate jars/builds for legacy Spigot 1.16–1.19, Spigot 1.20–1.21, Paper 1.21+, and Folia 1.21+). Use the build matching your server.
• Database backends supported: SQLite, MySQL, MariaDB and PostgreSQL (used for storing account data).
• Some features require additional integration: PacketEvents is required for direct premium bypass and some inventory-protection features; proxy installations normally rely on proxy modules for Velocity/BungeeCord.
• The project is open source and distributed under GPL-3.0.

🤝 When This Plugin Is Useful

If you need server-side authentication (for offline-mode servers) or a configurable login system with session handling, 2FA and database-backed accounts, AuthMeReloaded provides the required features and multiple platform builds to match modern server setups.
