Password security on report level

Some organisations use power bi to create reports and share the public URL with other organisations. In cases of marketing consultancy for example. Their clients share their data with the bureau to get back insights in a report. Once this report is published its public and all over the world wide web. It's very hard to get there by coincidence, but it's possible. It would be super great to secure such reports with a password or some like that. A way to give these clients a safe and secure feeling about their shared data.
