Password Protect CMS Page

to protect any page with a password in an easy way you can add this script to the top of the page

<script type="text/javascript">
    var password = 'password123'
    var retVal = prompt("Enter your password : ", "your password here");
    if(retVal !== password)
    {
        location.assign('');

app\design\frontend\{vendor}\{theme}\Magento_Ui\web\js\view\messages.js

then modify this function 

You can use this script to detect the screen size as you want
