Extension Metadata

About this extension
LegendPass Vault is a secure password manager that syncs seamlessly between your browser and mobile app.

Features:
• Auto-detect and autofill login forms on any website
• Store passwords, credit cards, and WiFi credentials
• AES-256 encryption with PBKDF2 key derivation (310,000 iterations)
• End-to-end encrypted sync across devices via cloud
• Mobile approval for browser autofill — adds a second layer of security
• Right-click context menu for quick autofill
• Copy passwords to clipboard with auto-clear
• Auto-lock vault after inactivity

Your vault data is encrypted locally before syncing. Only you hold the master password — we never have access to your data.

Requires the LegendPass Vault mobile app (Android/iOS) for account creation and mobile authentication.
