SmartLogin
The Next-Gen Authentication, Identity & Cybersecurity Suite Minecraft Deserved

Engineered for modern Paper & Purpur 1.21+ | Powered by Java 21 & Argon2id OWASP Standard

️ WHY SMARTLOGIN?
"For almost a decade, server owners have been forced to use legacy authentication plugins conceived in 2015, filled with archaic SHA256 hashes, unoptimized queries, and boring chat-only prompts. We built SmartLogin from scratch to set a new standard in Minecraft server security."

⚔️ THE FEATURE MATRIX

Feature	SmartLogin	Legacy Plugins (AuthMe / nLogin)
Default Hashing Algorithm	Argon2id (OWASP Military-Grade, GPU-proof)	SHA256 / BCrypt / Plain MD5
Two-Factor Authentication (2FA)	Physical In-Game QR Code Map (5s scan)	Chat URLs / Secret String Copying
Bedrock / Floodgate UX	Tactile Touch PinPad GUI + Auto-Login	Clunky Chat Commands
Streamer Privacy Shield	Real-time Chat Interceptor + IP/Email Masking	None (Passwords leak if / is missed)
Account Recovery System	Autonomous Discord & Telegram Bots in 10s	Manual Admin Intervention / Email only
Engine Performance	100% Asynchronous (ForkJoinPool, 0.00% TPS Loss)	Partial Main-Thread Blocking
Database Migration	Universal Batch Migration (50k accounts in ~1s)	Manual SQL queries / Slow row-by-row

️ IN-GAME QR CODE TWO-FACTOR AUTHENTICATION (2FA)
No more painful secret keys in chat! Players receive a rendered in-game Minecraft map with a live QR code.

Instant 5-Second Pairing: Scan directly using Google Authenticator, Authy, Microsoft Authenticator, or 1Password.
Automated Map Clean-up: Maps are rendered purely client-side without cluttering item IDs or server world data.
Emergency Backup Codes: Players receive 5 encrypted one-time recovery codes to safeguard against phone loss.

---

BEDROCK & FLOODGATE NATIVE PINPAD
A world-class experience crafted specifically for mobile and console players.

Tactile Touch Numerical Keypad: Bedrock users enter their PIN with visual touch buttons instead of opening the chat keyboard.
Zero-Command Auto-Login: Cryptographically auto-authenticates linked Bedrock players seamlessly on join.

✨ MORE REVOLUTIONARY FEATURES

️ Next-Gen Argon2id OWASP Cryptography
The gold standard in modern cybersecurity. Configurable memory cost, time iterations, and parallelism to resist brute-force attacks from modern GPU farms and ASICs.
Autonomous Discord & Telegram Recovery Bots
Players link their accounts via /link or /tlink. If they forget their password, they reset it autonomously in 10 seconds through interactive bot buttons, eliminating 90% of support tickets for your staff team.
Streamer Anti-Leak Shield
Did a content creator forget the / slash and type their password into global chat? SmartLogin's pattern matching intercepts the packet before it reaches the server chat pipeline. Sensitive IPs and emails are masked in all GUIs.
⚡ Universal 1-Second Database Migration
Switching from another plugin? Run /smartlogin migrate all! High-speed SQL batch transactions import over 50,000 accounts in approximately 1 second from AuthMe, nLogin, FastLogin, CrazyLogin, xAuth, or LoginSecurity. Legacy hashes are automatically upgraded to Argon2id on player login.
Visual Admin Dashboard & Live Diagnostics
Manage players, unregister accounts, reset 2FA, benchmark CPU hashing speed, and audit real-time engine latency with interactive inventory GUIs (/smartlogin gui and /smartlogin diag).
