Security: authorization to embed dashboard with Power Bi Service

Good evening,

due to security reasons, it could be appropriate to require authentication when you embed a report or dashboard published in Power BI Service. Currently, this control is not supported.
It could be appropriate if a user that wish to share a dashboard or report (for example into a Web page) provided an access token, not allowing to see the dashboard without it.
Without this level of security, there could be lack of security, especially when you manage any sensitive data.

Best regards.
