Can I iFrame the Auth&Auth flow?
iFraming the Auth&Auth flow
The issue is we don't support iFrame, so we can't exactly fix and issues or give any support if you run into trouble. If you have to send users through the authorization flow, it would be best to take it out of the iFrame even from the first page. That is really the only solution we can suggest. If you must iFrame your authorization, you will have to do so at your own risk.
