Here is a full description on how to configure the 2FA:

Overview

Two-factor authentication (2FA) is an improved security measure that requires two forms of identification: your password and a generated security code. With 2FA enabled, an application on your smartphone supplies a code that you must enter with your password to log in. Without your smartphone, you cannot log in.

Configure two-factor authentication

To configure two-factor authentication, perform the following steps:

1. Click Set Up Two-Factor Authentication.
2. To configure two-factor authentication, you must create a "link" between your cPanel account and your 2FA app: 
   
   • To automatically create the link, scan the displayed QR code with your app.
   • To manually create the link, enter the provided Account and Key information into your app.

3. Open your 2FA app to retrieve the six-digit security code.

   Note:

    The 2FA app generates a new six-digit security code for your cPanel account every 30 seconds.

4. Enter the six-digit security code in the Security Code text box.

   Note:

   You must enter the security code within 30 seconds. After time expires, the app will generate a new six-digit code.

5. Click Configure Two-Factor Authentication.

Remove two-factor authentication
