A Windows-only 2FA TOTP key manager built with Tauri 2 (Rust backend + vanilla JS frontend).

Features

• TOTP Code Generation - Generate 6-digit time-based one-time passwords
• Multiple Import Methods:
  • Manual key entry (Base32 format)
  • QR code image import (supports multi-select)
  • Camera scanning
• Google Authenticator Migration - Import accounts from Google Authenticator export QR codes
• Secure Storage - Data encrypted with Windows DPAPI
• System Tray - Minimize to tray after copying, click tray icon to restore
• System Notifications - Get notified when codes are copied
• Account Deduplication - Automatic detection of duplicate accounts

Build Requirements

• Rust 1.75+
• Node.js 18+
• Windows 10/11

Development

# Install dependencies
npm install

# Run in development mode
cargo tauri dev

# Build for production (creates NSIS installer + APPX)
cargo tauri build

Data Storage

Account data is stored at:

%APPDATA%\totp-manager\keys.bin

Data is encrypted using Windows DPAPI (Data Protection API), which ties the encryption to the current Windows user account.

Tech Stack

• Backend: Rust + Tauri 2
• Frontend: Vanilla JavaScript + HTML/CSS
• TOTP: otpauth crate
• QR Scanning: jsQR (frontend) + rxing (backend)
• Encryption: Windows DPAPI
