Scenario: User have embedded Power BI reports into a Dynamics 365 portal using secure embedding. When users access the portal for the first time, they are prompted to sign in to Power BI. After authentication, the embedded report loads successfully. However, if the user refreshes the browser or opens the portal in a new tab, the embedded Power BI report again prompts for sign-in, even though the user is already authenticated in the Dynamics 365 portal session. Current Behavior / Limitation: This behavior aligns with the current design of secure embedding, where Power BI authentication is handled separately and does not persist across browser refreshes or new tabs. This limitation is documented in Microsoft Learn: Embed a report in a secure portal or website - Power BI | Microsoft Learn As a result, users are required to repeatedly authenticate to Power BI, leading to a suboptimal user experience. Idea: The user expects a seamless single sign-on (SSO) experience, where users who are already authenticated into the Dynamics 365 portal can view the embedded Power BI report without being prompted to sign in again, even after refreshing the page or opening a new tab.
