Two Factor Authentication (2FA), I hope you are aware of this term. Brute force attacks are very common in the internet world. Normally, attackers try to guess your Password by submitting words and letter combinations.
They do it manually or by bot also. If they find your password by any means then your site’s access will be in their hands also.
After that, you can imagine the risk. To optimize the security of your site you must take all the necessary measures. Two Factor Authentication may also be one of the major step to secure your site.
What is Two Factor Authentication & How it Works?
Normally when you log in to your website dashboard, you need to put your User Name and Password. The server recognizes your credential if it matches then you get the access.
But in case you implement Two Factor Authentication then you need an additional unique code to log in.
After implementing 2FA, you just have an additional security layer. After this, you can’t log in to your WordPress site with user name and password only.
Now You have to put the second factor also. That is a unique authentication code. Means if you want to login your site after 2FA then you need the following things:
- User Name or Login ID
- TOTP (Unique Authentication Code)
Now, suppose someone or attackers got your user name and password by any means. But whenever they will try to log in to your site then there will be a requirement for a unique authentication code.
It is because of an additional layer of 2FA. This required an additional unique code that only you can generate through an authentication app on your Mobile.
How to Implement Two Factor Authentication in Your WordPress Site?
If you want enable Two Factor Authentication in your WordPress site then you need two things:
- Two Factor Authentication Plugin
- Two Factor Authentication App in Your Mobile
You download an authentication plugin in WordPress and activate it. Do the setting as per your requirements. You can download Wordfence, Google Authenticator Plugin, or any other 2FA plugin as per your choice.
After that, you install the authenticator app on your mobile. Open your app and you just need to scan the bar code showing in your authenticator plugin and add your site in the app.
There will be a verification code just fill it in the app and verify it in the plugin. Your site will be added.
Now whenever, you will log in to your WordPress dashboard then you have to enter your User Name, Password and click on login. After clicking on login there will be a window to fill 2FA code.
You just open your app on the mobile and you will see a TOTP. Enter the code to get a login to your site’s dashboard.
What is the Difference Between Two Factor Authentication and Single Factor Authentication?
In Single Factor Authentication, you only need Login ID/User Name and Password to login your WordPress. But in the case of Two Factor authentication, there is a third layer also.
In this case you need Login ID/User Name, Password and TOTP ( Time based One Time Password)
What is TOTP?
Mostly, the Two Factor Authentication plugin works on TOTP protocol. TOTP is a time-based One Time Password. You need to have an app that supports this protocol. For example, the Google authenticator plugin supports the TOTP protocol.
Normally, this one-time password is valid for 30 seconds only. You will notice that code change every few seconds (30 seconds) on your mobile app.
