If you don’t want to require logging in to access projects, you can provide clients with a direct link to the project instead.
Unless you want this to be a publicly available project, we recommend keeping the “hide from search engines” setting left on.
Once you’ve created the project, you can simply copy and paste the project web address into an e-mail, Slack or other communication tool. For example, if you have a project located at http://www.yourdomain.com/panorama/website-redesign-for-company-xyz you can just send them that link directly.
NOTE: Using this method you will be unable to assign users to the project preventing the assignment of tasks or sending of notifications.
