Power BI 'Act As functionality'

Hi DebbieE 

Thank you for reaching out to the Microsoft Community Forum.

Power BI does not have an equivalent to OBIEE’s Act As / Proxy functionality. In Power BI (including Premium and Fabric), all security is always evaluated against the signed-in Entra ID identity and that identity cannot be temporarily overridden. This is a hard architectural boundary. There is no supported way for a user to impersonate another user, either to see more data or to see less data, while remaining logged in as themselves.

As a result, organizations needing OBIEE-style proxy behavior use external workarounds. The most common method is to create dedicated test or audit accounts that match a real user’s security settings, allowing admins or executives to sign in for validation or troubleshooting. Another approach is to temporarily change security group membership in a controlled and auditable manner. Currently, Power BI does not provide a built-in, user-driven “act as” feature.
