Login for small iframe embeded panels

I have some panels embeded on a mobile website from different IP/Hostname.
Problem: The Grafana Login screen need min 450 px to show logo/user/password, my panels are just 200 px in height. Is there a way for a smaller login window/modal/whatever. I have no problem with the Grafana logo and i don’t want to recode on every Grafana update.
Or is there a redirect to a login page or somethin i don’t think about? I dont want the Google OAuth.

Any hints/thoughts?
