Welcome to XD3 PassVault & 2FA, the ultimate zero-knowledge, offline-first security vault engineered by XDCyber tech. Designed for absolute privacy, XD3 ensures that your secrets, passwords, and 2FA tokens never leave your device unless you explicitly export them. There are no cloud servers, no telemetry, and no third-party tracking—just uncompromising security.

🛡️ MILITARY-GRADE ENCRYPTION
• Zero-Knowledge Architecture: Your vault is encrypted and decrypted locally on your device. We never have access to your Master PIN or your data.
• AES-256-GCM Encryption: All vault items are secured using the industry-standard Advanced Encryption Standard with Galois/Counter Mode for authenticated encryption.
• Advanced Key Derivation: Your Master PIN is protected by PBKDF2 (HMAC-SHA256) with 100,000 iterations and cryptographic salt to thwart brute-force attacks.

🔐 INTEGRATED 2FA AUTHENTICATOR
• Stop using multiple apps. XD3 includes a built-in Time-based One-Time Password (TOTP) authenticator.
• Quickly scan QR codes to instantly add 2FA tokens to your vault.
• Seamlessly view rotating 6-digit codes directly alongside your login credentials.

📊 SECURITY AUDIT & HEALTH CHECK
• Proactively monitor your digital security with the built-in audit engine.
• Instantly identify weak, vulnerable, or reused passwords across your entire vault.
• Color-coded health metrics guide you on which accounts need immediate updating.

⚙️ ADVANCED PASSWORD GENERATOR
• Create virtually unbreakable passwords on the fly.
• Fully customizable entropy: adjust length, uppercase, lowercase, numbers, and special symbols.
• One-tap save directly into your secure vault.

🗄️ SECURE BACKUP & RESTORE
• Encrypted Vault Exports: Back up your entire vault as an AES-256 encrypted JSON file. Protect it with a custom PBKDF2 password (65,536 iterations) for safe storage on USB drives or personal clouds.
• Plaintext CSV/JSON Export: Need to migrate? Export your data to standard formats (Strictly protected behind Biometric Authentication to prevent unauthorized physical access).

👁️ ULTIMATE PRIVACY & ACCESSIBILITY
• Biometric Unlock: Seamlessly access your vault using Fingerprint or Face Unlock, securely tied to the Android Hardware Keystore.
• Screen Protection: Toggle "Screen Shield" to block screenshots, screen recording, and prevent your passwords from appearing in the Android recent apps switcher.
• Auto-Lock: Configurable timeout automatically locks the vault the moment you step away or background the app.
• Fully Offline: Works perfectly in airplane mode. No internet permission is required to manage your core vault.
