Can I publish a sheet and password protect the link?

I would like to publish a link and share a link to where an outsider does not have to sign up for a Smartsheet account, however, they must enter a password to be able view/interact with the sheet. I


  1. I share link
  2. I set the password
  3. I have a custom domain fwd to the shared link.
  4. Customer goes to link, enters password, and is able to access the sheet and view and edit the sheet. No Smartsheet signup required.

I have this set up with Dropbox currently and it works great. Except I'd like to be able to leverage sheets for organization, correspondence (via message feature for each cell), and file storage (under each cell).

I want to provide the best customer experience and this includes not having to sign up for smartsheet to access the spreadsheet.
