I'm not a programmer but have done some scripting so I know a little at what I'm looking at.

Modified the adobepass.py with the following:

'ABB': {
        'name': 'Atlantic Broadband',
        'username_field': 'username',
        'password_field': 'password',
    },

I wanted to see if it would just work out of the box.

Here is the result:

I feel like I need to modify something to get it further so that is why I'm reaching out.

I'll gladly work on this my self, just need some help.  I can also create a sub email account that one the developers could use to also test.  Thanks for your help.
