No, this option can be used with anonymous, public users. When selected, this allows the user to provide an email address and password so they can access the form again. A link to the form is sent to the specified email address.

As for specifying the date in/date out, you could simplify the proctor's life by creating some simple buttons that, when clicked, enter the current time in a field.

Create two single line fields, one for time in, one for time out. Add the timeIn class to the time in field, add the timeOut class to the time out field.

Here's the HTML you'll use in a Custom HTML field to create the buttons

<input class="inButton" value="Sign In" type="button"> 
<input class="outButton" value="Sign Out" type="button">

Here's the JavaScript.

$(document).ready(function () {
  $('.inButton, .outButton').click(timestamp);
 
  function timestamp() {
    
    var d = new Date();
    var minutes = d.getMinutes();
    
    if (minutes < 10) {var minutes = "0" + minutes;}
        
    if (d.getHours() < 12) { var a = "AM";}
    else {var a = "PM";}
      
    if ($(this).hasClass('inButton')) {
      $('.timeIn input').val(d.getHours() + ":" + minutes + a);
    }
    
    else {
    
    $('.timeOut input').val(d.getHours() + ":" + minutes + a)
    
    }
  }
});

Edit: Updated the JavaScript to account for leading zeros for minutes under 10.
