A project in Advanced Server Access is an authorization scope, similar to a domain in Active Directory, or a realm in Kerberos.
A project associates a collection of resources with a set of configurations, including Role-Based Access Control (RBAC) and access policies.
Projects are used to manage access to Windows servers, Linux servers, or web applications. You can think of a project as a programmable Certificate Authority for client certificates, including OpenSSH CA certificates and X.509 certificates, as well as signed objects such as JWTs.
No matter what you choose to secure with Advanced Server Access, you'll need to create at least one project.
