🛠️ Technical Details

The Google Authenticator Exporter utilizes several technologies to provide a seamless experience:

• Framework: Built with React and TypeScript for reliable, type-safe code
• OTP Implementation: Uses the otpauth library for TOTP/HOTP generation
• QR Scanning: Implemented with the HTML5-QRCode library
• Protobuf Parsing: Decodes Google Authenticator's migration format using protobufjs

📋 How to Use

1. Visit the app in your browser
2. Allow camera access when prompted
3. Scan a Google Authenticator QR code:
   • Single account QR code
   • Migration QR code (multiple accounts)
   • Any standard otpauth:// QR code
4. View your authentication details
5. For TOTP accounts, watch the code refresh with the countdown timer
6. Copy the code, secret, or export to your preferred format
