How to Disable 2F Authentication in Magento 2?

Magento Two-factor Authentication is one of many ways to improve Magento admin security and prevent unauthorized access to your data. Correspondingly all admin users have to complete the authorization process to verify their identity before logging in.

Two-Factor authentication is available in the latest Magento 2.4 version by default and supports multiple authenticators like Google Authenticator, Suo, Authy, and U2F keys. So it is easy for you to configure it and generate access codes for different users to add an additional layer of security.  

However, if your website is in the development stage or if you work on the testing environment you might need to disable two factor authentication in Magento.

To disable 2F Authentication in Magento 2 you just need to run the following command:

php bin/magento module:disable Magento_TwoFactorAuth

Note: it is not recommended to disable two-factor authentication unless you have to.

If you want to grant some developers access to your installation so they can debug some issues or assist you in fixing them, there is also a way to disable Magento 2F Authentication for a specific user

It requires some coding though, so you might need to call out for a developer on this one.
