How Google’s Titan M chip makes the Pixel 3 its most secure phone ever

  • Google has discussed its new Titan M security chip found in its soon-to-be-released Pixel 3 phones.
  • The custom chip is designed to add an extra layer of protection to the Pixel 3 to keep your device and data safe.
  • It makes hijacking or tampering with a Pixel 3 more difficult with several smart systems

Google says the Pixel 3 is its most secure phone yet and it’s thanks to a new chip, the Titan M. The Mountain View company detailed its custom-built chip in a blog post yesterday, outlining three key ways in which the chip aids the Pixel 3’s security.

The first of these relates to the bootloader. The Titan M works in conjunction with its Verified Boot system as an extra layer of defense against hackers and other attacks. This helps ensure that the version of Android booted up on the device is safe and hasn’t been tampered with or rolled back to a previous, less secure version.

It’s also said to prevent hackers unlocking the bootloader, but what that means for device owners wanting to unlock their bootloader intentionally, we don’t yet know (I expect this will still be possible, though).

Editor’s Pick

The Titan M also integrates with the Pixel 3’s lock screen passcodes, limiting how many login attempts can be made. This should make it more difficult for people to spam password combinations to gain access to another person’s device, but Google doesn’t explain exactly why the Titan M is necessary for limiting these login attempts. Android already has systems in place to dissuade false login attempts, like locking you out of the handset if you fail a few in quick succession. Seemingly, the Titan M offers a more sophisticated version of this, but to what extent we can’t say.

Additionally, the chip’s secure flash and fully independent computation make it more difficult for hackers to decrypt your data.

Editor’s Pick

Google has also tackled transaction security in third-party apps with the Titan M. The chip supports Android Pie’s StrongBox KeyStore and Protected Confirmation APIs to store private keys and ensure real users are confirming transactions (not malware bots).

Finally, the Titan M is also built on Android’s Insider Attack Resistance security module, said to make it harder to bypass the lock screen and tamper with the firmware.

Wrap up

These all sound like positive moves, but there are some interesting implications. One is that the Android itself isn’t completely secure, as it benefits from additional hardware protection. However, this could perhaps be said of all major software platforms, and hardware security systems are becoming more common as an extra defence.

The other implication relates to Android OEMs. For much of Android’s security systems, third-party manufacturers are at Google’s mercy. Android may be a comparatively secure ecosystem, but with Google adopting — and by proxy, advocating — security chips, other companies might feel obligated to follow suit. This could be good news for Android fans, but it could also inflate prices.

How to Easily Add JavaScript in WordPress Pages or Posts (3 Methods)

Do you want to add a JavaScript in your WordPress pages or posts? Sometimes you may need to add a JavaScript code to the entire website or into specific pages. By default, WordPress does not let you add code directly in your posts. In this article, we will show you how to easily add JavaScript in WordPress pages or posts.

How to easily add JavaScript in WordPress posts and pages

What is JavaScript?

JavaScript is a programming language that runs not on your server but on the user’s browser. This client-side programming allows developers to do a lot of cool things without slowing down your website.

If you want to embed a video player, add a calculator, or some other third-party service, then you will be often asked to copy and paste a JavaScript code snippet into your website.

A typical JavaScript code snippet may look like this:

<script type="text/javascript"> 

// Some JavaScript code

</script>

<!-- Another Example: --!>  

<script type="text/javascript" src="/path/to/some-script.js"></script>

Now, if you add a javascript code snippet to a WordPress post or page, then it will be deleted by WordPress when you try to save it.

That being said, let’s see how you can easily add JavaScript in WordPress pages or posts without breaking your website.

Method 1. Add JavaScript Site-Wide Using Insert Headers and Footers

Sometimes you will be asked to copy and paste a JavaScript code snippet into your website to add a third-party tool. These scripts usually go to the head section or at the bottom before the </body> tag of your website. This way the code is loaded on every page view.

For example, Google Analytics installation code needs to be present on every page of your website, so it can track your website visitors.

You can add such code to your WordPress theme’s header.php or footer.php files. However, these changes will be overwritten when you update or change your theme.

That’s why we recommend using a plugin to load javascript on your site.

First, you need to install and activate the Insert Headers and Footers plugin. For more details, see our step by step guide on how to install a WordPress plugin.

Upon activation, you need to visit Settings » Insert Headers and Footers page. You will see two boxes, one for the header and the other for the footer section.

Insert Headers and Footers plugin settings

You can now paste the JavaScript code you copied to one of these boxes and then click on the save button.

Insert Headers and Footers plugin will now automatically load the code you added on every page of your website.

Method 2. Adding JavaScript Code Manually Using Code

This method requires you to add code to your WordPress files. If you haven’t done this before, then please see our guide on how to copy and paste code in WordPress.

First, let’s take a look at how to add code to your WordPress site’s header. You will need to add the following code to your theme’s functions.php file or a site-specific plugin.

function wpb_hook_javascript() {
    ?>
        <script>
          // your javscript code goes
        </script>
    <?php
}
add_action('wp_head', 'wpb_hook_javascript');

Adding JavaScript to a Specific WordPress Post or Page Using Code

Let’s suppose you only want to load this javascript on a specific WordPress post. To do that, you will need to add conditional logic to the code. Take a look at the following example:

function wpb_hook_javascript() {
  if (is_single ('16')) { 
    ?>
        <script type="text/javascript">
          // your javscript code goes here
        </script>
    <?php
  }
}
add_action('wp_head', 'wpb_hook_javascript');

If you take a closer look at the code above, you will see that we have wrapped javascript code around conditional logic to match a specific post ID. You can use this by replacing 16 with your own post ID.

Now, this code would work for any post type except for pages. Let’s take a look at another example except this one will check for a specific page ID before adding the javascript code to the head section.

function wpb_hook_javascript() {
  if (is_page ('10')) { 
    ?>
        <script type="text/javascript">
          // your javscript code goes here
        </script>
    <?php
  }
}
add_action('wp_head', 'wpb_hook_javascript');

Instead of is_single, we are now using is_page to check for page ID.

We can use the same code with slight modification to add javascript code to your site’s footer. Take a look at the following example.

function wpb_hook_javascript_footer() {
    ?>
        <script>
          // your javscript code goes
        </script>
    <?php
}
add_action('wp_footer', 'wpb_hook_javascript_footer');

Instead of hooking our function to wp_head, we have now hooked it to wp_footer. You can also use it with conditional tags to add Javascript to specific posts or pages.

Method 3. Adding Javascript Code Inside Posts or Pages Using Plugin

This method will allow you to add code anywhere inside your WordPress posts and pages. You will also be able to select where in the content you want to embed the javascript code.

First, you need to install and activate the Code Embed plugin. For more details, see our step by step guide on how to install a WordPress plugin.

Upon activation, you need to edit the post or page where you want to add the javascript. On the post edit page, click on the ‘Screen Options‘ button and check the ‘Custom Fields’ option.

Show custom fields meta box

Now scroll down and below the post editor, you will see the ‘Custom Fields’ metabox where you need to click on the ‘Enter new’ link.

Add a new custom field

The custom field name and value fields will now appear.

You need to provide a name for the custom field with a CODE prefix (for example, CODEmyjscode) and then paste the javascript code in the value field.

Adding a JavaScript code to a custom field

Don’t forget to click on the ‘Add Custom Field’ button to save your custom field.

Now you can use this custom field to embed the JavaScript code anywhere in this post or page. Simply add this embed code anywhere in your post content.

You can now save your post or page and view your site. You will be able to see the javascript code by using the Inspect tool or by viewing the page source.

Tip: These methods are for beginners and website owners. If you are learning WordPress theme or plugin development, then you need to properly enqueue JavaScript and stylesheets to your projects.
