dbashlak on "[Theme: Hueman] oauth code in theme"

Hi!
Thanks for your theme, but I'm a little bit worried about this code at the bottom:
iframe name="oauth2relay83346456" id="oauth2relay83346456" src="https://accounts.google.com/
(it's not the full code, just for you to see, what I'm talking about).
What is this for? It's not from any plugin as far I can see and not from wordpress itself.
