Connecting wink to hass.io, login credentials?

I’m trying to connect hass.io to Wink. I have a developer account and the setting seem to be correct because the backend prompts me to Authorize and when I click the link I get this:

However, I log into my wink developer account through GitHub… so I don’t have a username and password like it’s asking for. My username for GitHub isn’t an email address, so this form won’t even allow me to submit my GitHub credentials. How do you guys get past this screen?

I did try resetting password, but when I put in my email address, it never sends me a recovery email.

Signing into the wink developer portal using a regular username/password (i.e. not through GitHub) does not appear to be an option.
