Final answer:
Unauthenticated requests to a front-end website are bound to the Anonymous user, providing limited access without identification.
Step-by-step explanation:
The user bound to unauthenticated requests to a front-end website is typically referred to as an Anonymous user. This means that the system does not have any identifying information about the user, as they have not logged in or provided credentials. When such unauthenticated requests are made, the front-end interfaces of web applications are designed to recognize these users as anonymous. They are usually provided with limited access to resources, often just enough for them to decide whether they want to sign up or log in for more privileges. In no case is an unauthenticated request bound to an authenticated user, admin user, or superuser, as these roles require authentication and are associated with specific permissions and access rights.
