When a user enters in a correct reCaptcha code, it is not necessary for the user to enter this in again if entered correctly. If a user enters in a valid reCaptcha code but then receives a validation error, such as "Required: First Name", the user does not need to re-enter this information. Unless the user completely closes the browser, clears their browser cache, or navigate away from the page and back, the reCaptcha code initially entered is valid for that session.
