@Hubmate - What documentation did you find these tags in? I don't recall seeing those anywhere. The password_prompt tag is used for the protected pages.
I contacted Hubspot Support about the tags and they told me they are used internally but not yet available for customers. There are a whole bunch of interesting tags that are not found in the official documentation. Click 'HubL reference' in the bottom right of the code editor and have a look through. See attached screenshot (highlighted in yellow).
