Embedding to web with authentication

Is it possible to embed a Power BI report to web with authentication? Since it only embed the URL  generated by Power BI Service, in the frames etc.. Now anyone having access to this URL will have access to the report. I am bedding the code in Google Site. Is it possible to put an "authentication requirement" for anyone to access wither the URL in power BI or on Google some how. ?

Thanks
