This is related to MMM-iFrame, but the issue comes from the Electron app.

Platform: Rapsberry Pi 3
Node Version: 10.15.0
MagicMirror Version: lastest
Description: Chrome doesn’t support the auto login syntax (user:pass@host) in iFrames anymore. In my case, I can’t display a webcam feed inside an iFrame with MMM-iFrame with the user:pass@host syntax.
Steps to Reproduce: install MMM-iFrame, try to add a webpage that needs basic auth.
Expected Results: the webpage shows up.
Actual Results: nothing shows up and a console log is issued: > [Deprecation] Subresource requests whose URLs contain embedded credentials are blocked
Additional Notes: if I open the Mirror with my web browser it prompts my creds and I can make my browser remember them. I also managed to open a new Electron tab, so I went directly to the webcam URL and the credentials were prompted ; but I can’t make Electron remember it.
Is there a way to give Electron basic auth informations?

I hope it is technically possible to solve the issue.
