AUCTION AUTH - The Ultimate Secure Login System

> Premium Auto-Login | Bedrock Bypass | Smart Teleport | 100% Customizable

Are you looking for a secure, lightning-fast, and smart authentication system for your PaperMC server? Auction Auth is not just another login plugin. It comes packed with smart auto-login for Premium and Bedrock (Geyser) players, an interactive BossBar countdown, and a flawless location memory system!
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✨ Key Features
Seamless Crossplay & Premium Auto-Login
* Bedrock Bypass: Bedrock players joining via GeyserMC (using prefixes like . or *) don't need to type passwords. They are instantly granted access to the server!

* Premium Java Auto-Login: The plugin automatically detects authentic Premium Minecraft accounts and lets them bypass the login screen entirely (Toggleable in config).
Smart Location Memory (Advanced Teleport System)
* Auth Spawn Lobby: Every unauthenticated player is instantly safely routed to a designated lobby upon joining (with a 3 ticks delay to prevent barrier-spawn glitches).
* New Players: Players who use /register for the first time will remain in the lobby so they can read the server rules or tutorials.
* Returning Players: Players who use /login are instantly teleported back to their exact previous location (where they last logged off)! (Can be disabled via teleport-back: false in config).
️ Ultimate Server Security (Total Freeze)
Until a player successfully logs in or registers, the plugin completely locks down their account to protect your server:
* ❌ Movement is completely frozen.
* ❌ PvP and PvE Damage (dealing or taking) is blocked.
* ❌ Item dropping and picking up is disabled.
* ❌ Block breaking, placing, and inventory clicking are blocked.
* ❌ Global chat is muted to prevent spam bots.
* ⏳ Max Attempts & Timeout: Automatically kicks players who fail to enter the correct password (default: 3 attempts) or run out of time (default: 60 seconds).
Stunning Visuals & Interactive BossBar
* Beautiful on-screen Titles, Subtitles, and Action Bar messages.
* Progressive BossBar: A sleek BossBar that visually decreases as the login timer counts down (Fully customizable color and style).
* Applies a temporary Blindness/Darkness effect to keep players focused on authenticating.
️ 100% Customizable (messages.yml & config.yml)
* Edit every single message, prefix, and color code to match your server's theme.
* Silent Mode: Want to disable a specific title, action bar, or message? Just leave it empty ("") in the config, and the plugin will safely ignore it!
Advanced Database & Admin Tools
* Supports both SQLite (Default) and MySQL.
* Powerful admin commands to view exact player passwords in-game, forcefully change them, or completely reset accounts.
