Duo One Time Password Generator

This is a little script I put together after I reverse engineered the Duo 2FA Mobile App and figured out how their auth flow works. This can be ported into probably a useful desktop app or chrome extention and can probably be used to write bots for MIT Services that require auth.

Usage

Install stuff,

pip install -r requirements.txt

Just grab the QR Code URL and copy the string after value

https://api-XXX.duosecurity.com/frame/qr?value={VALUE}

./duo_activate.py {VALUE}

If everything worked you can then generate a code by running:

./duo_gen.py

Warning: These are HOTP tokens and generate codes increments a counter. If you get too far out of sync with the server it will stop accepting your codes.

./duo_export.py

Export the duo hotp secret as a QR code for inclusion in third-party hotp apps like freeotp.
