Can I share dashboards with unregistered users?

Not directly by default -- you can purchase a "public publish" license (but the quote I got for that was way expensive), otherwise there are a couple of other options to share widget data (Excel, CSV, or GoogleSheet snapshots of widget data) or images/pdfs of a widget and/or whole dashboard. One is the built-in send-an-email of dashboard feature (pdf or in-line), while you will only be able send the email to registered users, you can set up your email to then re-forward that mail to anyone you want (I use an app called Zapier to do this, it looks for mails of a specific type and then forwards them), the other is that you can generate scripts in your SiSense to generate CSV or Excel or GoogleSheet of widget data and then mail that to whomever you want. In all these cases, however, the user does not have the Dashboard experience... to get that you need to register the user (or have the public license option). John
