 > Note: The credentials used in the example requests for the fake API from reqres.in are pre-defined and hardcoded, and therefore not validated in any way. This is because reqres.in is a mock API used for testing and development purposes, and is not intended for production use. In a real-world application, user credentials would need to be validated on both the client-side and server-side to ensure the security of user data.
