A small script to activate Duo's HOTP code

1. Register a new device

   • Select Tablet
   • Select Android
   • Select "I have Duo Mobile installed"

2. Right click the QR code, copy the image url, and then run this program with the QR code url.

   # example
   python main.py "https://api-xxxxxxxx.duosecurity.com/frame/qr?value=....-...."

3. You'll get your HOTP secret with a counter, which starts from 0.

• You can use a cli tool like oathtool to generate the passcode.

  # example
  oathtool --hotp -b 'base32' -c 0

• You cannot use some managers like 1Password since they do not support HOTP.
• Ensure that the counter is incremented every time you login.
• Other details: SHA1, 6 digits
