Summary

With the release of Magento 2.4, two-factor authentication (also known as 2FA) became enabled by default, with no
ability to disable it in either the admin or console. However, there are situations which may require 2FA to be disabled
or temporarily turned off, such as within development or testing environments.

This module automatically disables 2FA while in developer mode (since version 2.0.0), and adds the missing toggle to turn 2FA on or off from the admin for other environments. It does this by hooking into the core code in
a very seamless manner, just as would be done if this toggle existed in the core code. Installing this module should not
open any security holes, as it just works off of a simple config toggle which, if not present, falls back to the default
functionality.

You can also toggle 2FA back on while in developer mode, if you need to test your code functionality while 2FA is enabled.

Why

Why should you use this module? I hear all of the time that you can just disable Magento's 2FA module. There is a large inherent issue with doing this though.

When you disable a module, it updates the app/etc/config.php file with the removed module, which will eventually make its way upstream (accidentally committed to version control or unintendedly leaving your development environment). This will disable 2FA on staging/production, which is a big security concern. This module resolves this because you can keep it installed & enabled on dev/stage/prod, but control whether or not 2FA is enabled or disabled with configuration settings or environment variables. This means you can have it permanently disabled on dev, but have it permanently enabled in all other environments, all while keeping this module installed in all environments.

Installation

composer require --dev markshust/magento2-module-disabletwofactorauth
bin/magento module:enable MarkShust_DisableTwoFactorAuth
bin/magento setup:upgrade

Usage

This module automatically disables 2FA in developer mode (since version 2.0.0). In any other deployment mode, 2FA is kept enabled by default. This is to prevent any unexpected side effects or security loopholes from
being introduced during automated installation processes.

It is highly recommended to install this module as a dev dependency to avoid security warning reports from either Adobe Commerce or other production environments which run security checks. This can be done either by passing in the --dev flag when installing it with Composer, or by adding it to the require-dev property of your composer.json file.

Disable 2FA

It may still be desirable to disable 2FA in non-production environments, such as within testing or internal staging environments. For these cases, 2FA is not automatically disabled. However, there are toggles to override the default Magento settings to disable 2FA within these environments.

You can also bypass 2FA for API token generation. This can be useful for third-party vendors during module development.

NOTE: Always keep 2FA enabled within production environments for security purposes.

2FA

To disable 2FA, visit Admin > Stores > Settings > Configuration > Security > 2FA and set Enable 2FA to No.

CLI: bin/magento config:set twofactorauth/general/enable 0

2FA for API Token Generation

To disable 2FA for API Token Generation, visit Admin > Stores > Settings > Configuration > Security > 2FA and set Enable 2FA for API Token Generation to No.

CLI: bin/magento config:set twofactorauth/general/enable_for_api_token_generation 0

Enable 2FA in developer mode

This module automatically disables 2FA while developer mode is enabled, but there may be situations when you need 2FA enabled during development. Rather than needing to disable this module, you can just disable this configuration setting in the admin.

To enable 2FA while in developer mode, visit Admin > Stores > Settings > Configuration > Security > 2FA and set Disable 2FA in Developer Mode to No.

CLI: bin/magento config:set twofactorauth/general/disable_in_developer_mode 0

The format is based on Keep a Changelog
and this project adheres to Semantic Versioning.

[2.0.2] - 2024-11-05

Added

• Added PHPStan level 9 support by improving type hints (#27)
• Added keywords to composer.json for better package discovery

Updated

• Updated installation instructions to recommend using --dev flag with composer
• Made package explicitly development-focused to avoid Adobe Commerce security warnings (#28)
• Updated badge icon with support for newer versions of Magento

Fixed

• Fixed issue where 2FA could remain enabled for API token generation when main 2FA was disabled (#29)

[2.0.1] - 2022-10-24

Fixed

• Fix compatibility with MFTF 3.10.0 (#16)

[2.0.0] - 2021-11-10

This is a potentially breaking release, as it changes the overall functionality when Magento is in developer mode. A new "Disable 2FA in Developer Mode" system configuration has been created, which is a Yes/No toggle. By default, it is set to Yes so that 2FA is automatically disabled when a Magento site is in developer mode. When this is set to No, the two other 2FA configuration dropdowns set the configuration for 2FA. When not in developer mode, this toggle has no effect.

Added

• Add ability to automatically disable 2FA when in developer mode (#13).
