Facebook Checker v1.0

A high-performance desktop application for validating phone numbers and email addresses against Facebook's account recovery system. Designed for bulk processing with multi-threaded execution, proxy support, and automatic session management.

---

Features

• Bulk Validation — Load millions of leads from a text file and validate them against Facebook accounts
• Multi-Threaded — Unlimited thread count for maximum throughput
• Auto Session Management — Sessions are created, rotated, and refreshed automatically with no manual configuration required
• Instant Start — Checking begins within seconds; additional sessions are created in the background while processing is already running
• Proxy Support — HTTP and SOCKS5 proxy support with automatic proxy testing and rotation
• Smart Fingerprinting — Rotates User-Agent, TLS fingerprint, cookies, and browser identity per session to avoid detection
• Memory Efficient — Streams leads from file instead of loading into memory; handles millions of entries without crashing
• Log Window — Live color-coded results (green = valid, red = invalid, orange = error) capped at 100 lines to save memory
• Background Session Refresh — Each session refreshes individually after a set number of requests without interrupting the checking process
• Output Options — Save valid/invalid results to custom filenames in the results/ folder; optional checkbox to include account name in valid output
• HWID Authorization — Hardware-locked licensing system for access control
• Cross-Platform — Compiled as a standalone .exe for Windows; no Python installation required
