Code update

[sfalvey]

Looks like the activation process has got a little less obfuscated.

To fix:

Remove the following lines....

data = unquote(qr_url.split('=')[1])
hostb64 = data.split('-')[1]
host = base64.b64decode(hostb64 + '='*(-len(hostb64) % 4))
code = data.split('-')[0].replace('duo://', '')

Add the following lines in their place

host = qr_url.split('/')[2].split('-')[1]
code = qr_url.rsplit('/',1)[1]
