Pro teams can now enable Password Protection for $20 per project per month. It requires visitors to enter a password you set to view the project's deployments.
Previously, Pro teams needed to purchase password protection for every project at the team level, but now it can be purchased individually.
To enable Password Protection for a project, open Security in the sidebar, select Deployment Protection, and turn it on. Disable it to stop future charges for that project.
