When it comes to a project, there are two main options for sharing settings: public or private. The private sharing setting limits access to only specified users and teams. By default, all new Synapse projects are set to private, and you can manually add collaborators and/or allowed users as needed. You can then specify individual permissions for any of these private users. If you set your project to public, you can also specify permissions for any registered Synapse user, as well as to allow anyone on the web to view an item (more on permissions below).
To view and modify sharing settings on a project, go to that project and click Project Settings in the top right corner, and select Project Sharing Settings from the resulting dropdown menu.
