What does cookie authentication involve?

• A. Using API keys
• B. Embedding data in HTTP request headers
• C. Configuring a secure token
• D. Utilizing biometric verification

Answer: (B)

Cookie authentication involves embedding data in HTTP request headers. This method uses cookies to store a user's session information and other credentials, which are then sent along with HTTP requests to authenticate a user. When a user logs into a web application, the server creates a session and sends a cookie to the user's browser. The browser stores this cookie and includes it in subsequent requests to the server. Using cookie-based authentication allows the server to maintain state over stateless protocols like HTTP, enabling the server to identify and authenticate a user based on the information contained in the cookie. This information typically includes session identifiers that relate to stored server-side data, enabling seamless user experiences without requiring repeated logins. By contrast, other authentication methods like API keys or secure tokens have different mechanisms for verifying identity, and biometric verification involves physical attributes rather than web/browser interaction, which is beyond the scope of cookie authentication.
