Using Two-Factor Authentication (2FA) with Magento is necessary for security because it adds an extra layer of protection to the authentication process.
For regular admin access to Magento, users are required to enter a username and password to access their account. However, this method can be vulnerable to brute force attacks or password guessing, especially if users are not using strong and unique passwords.
Typically Google’s reCAPTCHA can be enabled and the login URL can be changed from /admin on the admin login page, which provides some protection but 2FA provides a significant improvement to your site’s security.
2FA adds a second layer of authentication by requiring users to provide an additional piece of information to verify their identity. Typically, this second factor is something that the user has, such as a mobile device, token, or security key.
By requiring this additional piece of information, even if an attacker manages to obtain the user's password, they would still need access to the second factor to gain access to the account.
In the case of Magento (either Open Source or Adobe Commerce versions), 2FA can help protect sensitive customer and payment data, which is critical for any eCommerce platform.
By using 2FA, Magento store owners and administrators can add an extra layer of security to their accounts, making it more difficult for attackers to gain access to sensitive information.
This can help protect against attacks such as phishing, brute force attacks, and password guessing, which are common methods used by attackers to gain unauthorised access to accounts.
One popular and widely used option for implementing 2FA in Magento is Google Authentication.
It is a free service provided by Google, and it works by using a mobile app, such as Google Authenticator or Authy, to generate a one-time code that is used in combination with the user's password to authenticate the user.
Once enabled, the user would be prompted to enter a one-time code from the app in addition to their username and password when logging in to their Magento account. This helps ensure that only authorised users with access to the linked mobile device can access the account, making it more secure.
Here’s how 2 Factor Authentication can be enabled on Magento Open Source and Adobe Commerce:
There are a number of legitimate reasons why a business might not want to have 2FA enabled. For example, if it causes issues with integrations (we’ve seen this with some of our clients and their bespoke ERPs) or internal teams may not have access to a “work” mobile phone to use the Google Authenticator App.
