What is Two Factor Authentication & How Does it Work?
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 your username and password only.
Now You have to put the second factor also. That is a unique authentication code. This 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 username 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.

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 log in to your WordPress. But in the case of Two Factor authentication, there is the 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 the 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.
