A. B.B.
Identity confirmation is still necessary even if a user's IP address is known and a browser cookie exists. This is because both the IP address and browser cookies can be easily manipulated or faked.
An IP address is a unique identifier for a device on a network, but it does not necessarily identify the individual using the device. It is possible for multiple people to use the same device and IP address, or for a single person to use multiple devices with different IP addresses. Additionally, IP addresses can be masked or hidden using a virtual private network ( VPN) or other tools.
Similarly, browser cookies can be manipulated or faked. Cookies are small text files that are stored on a user's device and used to track user activity and preferences. However, cookies can be deleted or altered, and it is possible for someone to create fake cookies that mimic the behavior of a legitimate user.
Therefore, identity confirmation is necessary to ensure that the person accessing the system is who they claim to be. This may involve asking for additional information, such as a username and password or a two-factor authentication code, to confirm the user's identity beyond just their IP address and browser cookie.
