GET YOUR STORE UPDATED to Magento 2.4 with the help of Magento Website Maintenance Experts to make the most of newest features.  

No.1 Improvement To Notice: Two Factor Authentication (2FA)

Hint for why this is the most important update: It’s the only thing Magento includes in its “preview and plan your upgrade” email. 


Hacking is becoming more and more prevalent in the ecommerce scene. Either a breach in customer personal information or trading secrets get leaked, you’ll face a massive crisis regardless of the business scale.

And take into account the current situation of social distancing and digitalized operation, it’s triple the threat of hacking. 

Not to mention, Adobe itself suffered both of these nightmares from a massive attack back in 2013

An in-depth investigation found 38 million active users IDs and passwords in jeopardy with the source code of several of Adobe’s products being stolen. 

That explains why, after the acquisition, we as Magento users have experienced attempts upon attempts to leverage Magento security for each update. 

For this 2.4 version, Magento focuses on one of the most common attack places – the login page. To do so, Adobe&Magento are providing and supporting multiple requiring areas for 2FA throughout the Magento Commerce ecosystem.

Don’t worry, we’ll learn about this tokenizing process right now.

What is two-factor authentication and how it works with Magento 2.4?

Here is the definition of TFA or 2FA:


With Magento, there are three gateways in which this verification tactics take places (and it is mandatory):

Further Security Enhancements With Sustainability

All 30 security advancements within Magento 2.4 are to help eradicate remote code execution (RCE) and cross-site scripting (XSS) possibilities.

Here is how these two types of attack differ:


For example, the 2FA we talked about earlier is mostly for RCE prevention by securing your login station. 

Other security improvements, including:

  • The template filter strict mode is now a default feature. Magento segments (counting CMS pages and hinders) that utilize the layout channel in inheritance mode can be helpless against distant code execution (RCE). Empowering exacting mode, of course, guarantees that RCE assaults can’t be purposely empowered.
  • Data rendering for UI data providers is now disabled by default. This removes any opportunity for malicious users to execute arbitrary JavaScript.
  • New \Magento\Framework\Escaper class. This class is provided for .phtml templates and the PHP classes that are responsible for generating HTML. 
  • *Support for new security.txt file**. This file is an industry-standard file on the server that helps security researchers report potential security issues to site administrators.

Security-only patch 

Note that Magento 2.4.0 is the primary quarterly discharge that gives the capacity to introduce security patches with no compelling reason to apply other utilitarian fixes. The new form of the stage offers to fix (Composer bundle 2.3.4-p2) that conveys all hotfixes applied to the 2.3.5 discharge.


Here are your direct access links regarding this topic:

  • For general information about this patch, check out this Magento dev docs article.
  • Learn how to download and install this security only patch using Composer – read up on this bit.

No More MySQL – Elasticsearch Will Power The Catalog Search Engine 

Using Elasticsearch instead of the default MySQL for faster layered navigation has been a  “big-brain” tip in a hot minute. You can do it in the following sequence  Stores -> Settings -> Configuration -> Catalog -> Catalog -> Catalog Search -> Search Engine.


In response, Elasticsearch will take over some workload from your database (which is managed by MySQL) and, in the same token, offer better performance – especially if you move it to a separate machine.

Understand that, Magento 2.4 will now set Elasticsearch as the default setting instead of MySQL. You and your customers can enjoy faster and more search capabilities with this improvement.


On this note, you need to make sure you have installed Elasticsearch 7.6.x first since it is the required version for Magento 2.4. But gladly, you can upgrade Elasticsearch effortlessly with caution for backup data and no migration issue by following this article.

In case you are using a third-party module for your search engine, you need to contact them and make sure their module is aligned with Magento 2.4 guidelines. 

This way, you can ensure a smooth transition into Magento 2.4.x.

Better Security Bug Recognition With CVE

Yes we have StackExchange, and yes we have GitHub community but that’s just simply not enough. Especially when we talk about security problems, we don’t need a mere vulnerability database. 

The bar is way higher than that. 

We need one system that allows internally linking of said vulnerabilities and facilitates the comparison of security providers and helpers. 


And Common Vulnerabilities and Exposures is the answer. Since Magento Commerce 2.3.2, Magento will acknowledge and record security bugs with the indexed CVE numbers. 

Come with that number identifier is a status indicator, a brief description, and references to related vulnerability reports and advisories. And such listings will make your ecommerce operation regarding vulnerabilities specification much easier. 

Say Goodbye To Authorize.Net And Braintree Payment Method Integrations

The Magento 2.4 will officially take these two payment method integrations out of the core code. If you still insist on including these payment gateways into your Magento system, you need to find the official extension on the Marketplace. 


Highlight Enhancements Of Magento Open Source & Commerce 2.4.0

Let’s get a summary of the most important area of Magento 2.4.0 upgrades.

A New Lock For Security

Besides the “unable to disable” 2FA for the Magento admin, we must talk about Content Security Policy (CSP).

As mentioned earlier, while 2FA is mainly for RCE prevention, CSP is all about XSS protection.

To be more specific, CSP within Magento will support whitelisting of inline style and script tags in .phtml templates. This feature is not universally permitted by the default configuration.

A New Platform Guideline

Magento 2.4 will set a new standard for platform workspace that is encompassed: 

  • Support for PHP 7.4. Magento 2.4 will still run with PHP 7.3, but it’s unrecommended. Noted, version 7.1 and 7.2 have been deprecated. 
  • PHPUnit 9.x from now on – 6.5 ver. has been deprecated. 
  • Elasticsearch 7.x will be the default setting for the catalog search engine.
  • MySQL 8.0 is the highly recommendation for use and MySQL 5.6 is out-of-date to host Magento 2.4.
  • Subsequently, MariaDB 10.0 and 10.1 are no longer supported – instead, turn to MariaDB 10.4.
  • Zend Framework dependencies are now migrated to the Laminas project.
  • The Signifyd fraud protection code has been removed from the core code. Install this official extension for replacement.
  • The core Braintree module, as discussed previously, will no longer a core code feature.

Improve The Quality Of Infrastructure

Firstly, because of the Payment Service Directive PSD2 and the proceeded with the development of numerous APIs, various Magento center installment mixes hazard getting obsolete and no longer security agreeable later on. 


With that in mind, many center installment mixes have been or will before long be belittled, and we are prescribing progress to their relating commercial center expansions. In this new era for Magento, these third party payment integrations will officially get removed: 

  • Worldpay
  • (Direct Post)
  • CyberSource
  • eWay

Besides, Magento 2.4 will also make a leap in these areas for infrastructure transformation:


These changes of direction are such important steps to set up a smoother and better ecommerce flow as well as execution. 

Attempts At Performance Optimization

Magento 2.4 will make a strike not only for the website but also for ecommerce performance. To be more specific, the test resulted in a 25-30% improvement with Quick Order add-to-cart performance.

  • Redis performance optimizations
  • More bite-size network data transfers 
  • Fewer CPU cycles consumption with prioritized automation
  • Fewer race conditions on Redis write operations
  • Improved caching for SQL queries: 1 query instead of 16.

In return, we will experience better performance within the Magento system, from loading to caching and even customer journey.

Adobe Stock Integration

Vendors now can discover any Adobe Stock see the picture in the Media Gallery, which decreases the number of steps required to permit stock review. 

It’s estimated that the introduction of Media Gallery will make the search-n-pick of Magento media assets 30x faster than previous versions.
