When the visibility of a project is Public, users access the project without the need for authentication. When visibility is Private, users must have at least View permission to access the project.
To obtain the sharing link to share a Public project:
Click on and then on Get project's public link. This function is inactive for projects with Private visibility type.
You can copy this link also from the project configuration interface. This is relevant when you make a project Public:
Click on and then on Edit to open the project configuration interface.
If you have Owner permission, check the Public box to make the project public. The icon appears next to the box.
Click on to copy the project share link to the clipboard.
