BAQ Report Password Protected

Has anyone had success creating a BAQ report and then making it password protected?

Id think this would have to be done withing SSRS.

We have this report email out daily using Report Style>Breaking and Routing.

You don’t have to
Simply put security on the baq (baq carries a security id) done and done

The report is formatted as an excel sheet via SSRS and then emailed to our exec team. We want to protect this report with a password.
