The concept of establishing or asserting the identity to the application is known as authentication. Authentication is the process through which a user, system, or application verifies their identity, typically involving the presentation of credentials, such as usernames and passwords, biometric data, or security tokens. This process ensures that the entity requesting access is indeed who they claim to be, thus enabling a secure interaction with the application.

In contrast, other terms like authorization pertain to determining what an authenticated user is allowed to do within the application, while identification is about recognizing who the user is, often preceding the authentication process. Verification, on the other hand, usually refers more to the process of confirming that the authenticated identity indeed matches the claimed identity, but it is not the initial step of asserting identity itself. Therefore, authentication is the most appropriate term when specifically discussing the assertion of identity within an application context.
