Basic authentication primarily uses what method of credentials?

• A. Username and password from an external system
• B. API token from Celigo
• C. Session cookie
• D. SSH key

Answer: (A)

Basic authentication primarily utilizes a combination of a username and password to verify the identity of a user. This method involves encoding the credentials in a specific format (usually Base64) and transmitting them as part of the HTTP headers during a request. The server receives this encoded information, decodes it, and checks the validity of the credentials against its user database. If the credentials match, access is granted. This method is straightforward and widely used in various applications and web services for its simplicity. While other methods, such as API tokens, session cookies, and SSH keys, are secure and useful in various contexts, they operate within different paradigms. For instance, API tokens provide a way to authenticate without directly using a username and password, session cookies are typically used to maintain state in a web session after initial authentication, and SSH keys are mainly employed for secure remote access rather than standard web authentication. Therefore, the use of a username and password as credentials is the defining characteristic of basic authentication.
