Walaupun blogspot ada fungsi invite readers only, tapi kita boleh set letak passcode untuk sesiapa yang nak akses blog kita.

Ini scriptnya

    <script type="text/javascript">
  var passcode = "YOUR_PASSCODE_HERE";
  var accessDuration = 60 * 60 * 1000; // 1 hour in milliseconds
  
  function passCheck() {
    var enteredPasscode = document.getElementById('pass').value;
    var errorMessage = document.getElementById('errorMessage');
    if (enteredPasscode === passcode) {
      var expirationTime = new Date().getTime() + accessDuration;
      localStorage.setItem('passcode', enteredPasscode);
      localStorage.setItem('expirationTime', expirationTime);
      document.getElementById('passDiv').style.display = 'none';
      document.getElementsByTagName('body')[0].style.overflow = 'auto';
      errorMessage.textContent = '';
    } else {
      errorMessage.textContent = 'Invalid passcode. Please try again.';
    }
    return false;
  }
  
  window.onload = function() {
    var storedPasscode = localStorage.getItem('passcode');
    var expirationTime = localStorage.getItem('expirationTime');
    var currentTime = new Date().getTime();
    
    if (storedPasscode !== passcode || currentTime > expirationTime) {
      localStorage.removeItem('passcode');
      localStorage.removeItem('expirationTime');
      document.getElementById('passDiv').style.display = 'flex';
      document.getElementsByTagName('body')[0].style.overflow = 'hidden';
    }
  };
</script>

Paparan lebih simple. Dengan passcode ini user tak boleh akses blog anda. Kalau dia ada passcodenya, dia boleh akses blog anda dalam 1 jam je. lepas tu akan lock balik. 

Letak code ini dalam tag body. Atau sebelum </body>

Ini untuk paparan passcode yang lebih minimalist.

 <script>
  // Define the passcode and access duration
  var passcode = "a";
  var accessDuration = 60 * 60 * 1000; // 1 hour in milliseconds

  // Function to handle passcode check
  function passCheck() {
    // Get the entered passcode and error message element
    var enteredPasscode = document.getElementById('pass').value;
    var errorMessage = document.getElementById('errorMessage');

    // Check if the entered passcode is correct
    if (enteredPasscode === passcode) {
      // Calculate the expiration time
      var expirationTime = new Date().getTime() + accessDuration;

      // Store the passcode and expiration time in local storage
      localStorage.setItem('passcode', enteredPasscode);
      localStorage.setItem('expirationTime', expirationTime);

      document.getElementById('passDiv').style.display = 'none';
