## 8 Configuring Authentication

Authentication means verifying the identity of someone (a user, server, or other entity) who wants to use data, resources, or applications. Validating that identity establishes a trust relationship for further interactions. Authentication also enables accountability by making it possible to link access and actions to specific identities.

Within a secure Oracle NoSQL Database, access to the database and internal APIs is generally limited to authenticated users. When a secure Oracle NoSQL Database is first started, there are no users defined, and login to the administrative interface is allowed without authentication. However, no data access operations can be performed without user authentication.
