1. Why are you saving userID to different UserRecord than you do with passwords and PINs? You created struct to hold all three pieces of information inside ONE variable

UserRecord fromPrompt;
bool foundMatch = false;
int count = 0;
do
{
    fromPrompt.userID = PromptID();
    fromPrompt.password = PromptPW();
    fromPrompt.PIN = PromptPin();
    foundMatch = FindMatch(fromPrompt, listOFUsers);
} while (count++<3 && foundMatch == false); 

2. Think about what does it mean for UserRecord type to be equal to another UserRecord, before you try to compare the two with equality operator "==".
You could probably start simple with something like this:

if ( file[index].userID == toBeMatched.userID ) 
{ 
    // If there is a user, check his password and pin
    if (file[index].password == toBeMatched.password &&
        file[index].PIN == toBeMatched.PIN )
    {
        matchFound = true;
    }
}
