Advanced Authentication System for Minecraft Servers
Discord: Tomas2193
PhoenixLogin is a complete authentication solution for offline-mode and hybrid Minecraft servers. It handles everything from registration and login to anti-bot protection, premium account detection, and visual captcha verification — all inside an isolated void world where unauthenticated players can't interact with your server.
Every password is hashed with BCrypt. Every database operation runs asynchronously. Every player state — inventory, gamemode, flight, location — is saved and restored perfectly through the authentication cycle.
No configuration headaches. Drop the JAR, restart, and your server is protected.
Features
Authentication
- Registration and login with BCrypt password hashing
- Configurable password requirements (length, uppercase, numbers, special characters)
- Session system with IP memory — returning players skip login
- Brute-force protection with temporary account lockout
- In-game password change and account deletion
- Auto-kick after configurable timeout
- Automatic detection of premium usernames via Mojang API
- Premium players can skip password login entirely with /premium
- Cracked players on premium names are handled gracefully with /cracked
- Premium status is remembered — future joins are instant
- Clear console warnings if the server is in offline-mode
- Connection rate limiting per IP
- Automatic attack detection with lockdown mode
- IP verification on first join (remembered for configurable days)
- Username validation and blacklisting
- Admin notifications for suspicious activity
- Map Captcha — renders a visual code on a map item the player holds
- Item Captcha — place a specific item in the correct inventory slot
- Math Captcha — solve a simple math problem (easy/medium/hard)
- Configurable per your server's needs
- Players authenticate in a completely isolated void world
- Unauthenticated players can't see or interact with your server
- Automatic world generation — no manual setup
- Full state preservation: gamemode, inventory, flight, and location are saved on entry and restored after login
- Custom spawn point via /setspawn
- Boss bar with real-time authentication countdown
- Titles and subtitles for login instructions and feedback
- Action bar timer with color-coded urgency
- Sound effects for login, registration, and errors
- Particle effects on successful authentication
- Login music system — vanilla sounds or custom .nbs files via NoteBlockAPI
- Full translations for English, Spanish, and Portuguese
- Switch language with one config change + /plogin reload
- Every single message is customizable per language file
- New messages from updates merge automatically without overwriting your edits
- Movement, interaction, chat, and commands are blocked until authentication
- Damage immunity (both received and dealt)
- Inventory and item drop prevention
- Players are hidden from each other during authentication
- Configurable command whitelist for unauthenticated players
- SQLite — zero configuration, works out of the box
- MySQL / MariaDB — connection pooling via HikariCP
- All queries run asynchronously — zero impact on server TPS
- Automatic schema migration between versions
- Login history tracking with automatic cleanup
