Two-Factor Authentication is a great way to secure your Magento admin area. Imagine if a hacker or someone else gains access to your backend? Not only could they destroy data and harass customers, but they could steal valuable business data and the end result could be customers lose confidence in your store. The best two factor authentication is using Google authenticator for Magento.
What is two-factor authentication?
Two-factor authentication increases the security of your Magento login by requiring an additional authentication method. Normally, you would input your password only. With two-factor authentication that is compatible with Google authenticator you would also input a 1 time access code in addition. This access code changes every 60 seconds, so it is nearly impossible to hack your login. By combining these two methods (two factors) your login is much more secure.
How do I enable two factor authentication for Magento?
You should install the Two-Factor Authentication Magento Extension for your store and then go to System -> Permissions -> Users and enable it for specific users.
