Bypassing the login for Supreset iframe in Webpage

I am using Superset version 0.15.1. I create a slice and use its iframe to embed into my webpage. When I do so, it directs me to superset login on the webpage.

Is there some way I can bypass the login or may be pass the credentials through iFrame in advance ?

I have tried removing the slice owner name, but that doesn’t quite work.

My Iframe is as follows :

      <iframe
