For cPanel & WHM version 62

(Home >> Security >> Two-Factor Authentication)

Overview

This function allows you to configure two-factor authentication (2FA), an improved security measure for the login interface of cPanel & WHM. Two-factor authentication requires two forms of identification:

  • Your password
  • A generated security code

When you enable 2FA, 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. For more information about 2FA, read Wikipedia's Two-Factor Authentication article.

Important:

If you or your users see a Failed to set user configuration: The security code is invalid. error, a problem may exist with the date and time settings on your server.

  • To fix the issue, use the ntpdate command to re-synchronize your server's internal clock with the Network Time Protocol (NTP) server.

  • 2FA requires an accurate server time in order to function properly.

Note:

2FA requires a smartphone with a supported time-based one-time password (TOTP) app. We suggest the following apps:

Enable 2FA

Warning:

This feature may cause some third-party applications to break significantly, and may cause applications to improperly store data.

If 2FA is disabled on the server, c lick the toggle to change it to On and enable 2FA.

Note:

Only the root user can enable 2FA.

Settings

The Settings tab allows you to configure the 2FA Issuer setting. The Issuer setting determines the name that appears in the authentication app when a user accesses the security code.

To customize the Issuer setting for 2FA, perform the following steps:

  1. Click the Settings tab.
  2. Enter the desired value for the Issuer setting, or retain the default value.

    Note:

    If you do not enter a name for the Issuer setting , it defaults to the hostname.

  3. Click Save.

Manage Users

The Manage Users tab displays the accounts for which you have configured 2FA, and allows you to disable 2FA on those accounts. 

Remove 2FA on a user account

To remove 2FA for a single user account on the Manage Users list, click Disable to the right of the user account.

To remove multiple user accounts from the Manage Users list, perform the following steps:

  1. Select the Manage Users tab.
  2. Select the checkboxes to the left of each user account that you want to remove, or select the checkbox to the left of the User heading to select them all.
  3. Click the gear icon () on the top right of the list, and then select Disable Selected.

    Note:

    Select Disable All to remove all user accounts from the Manage Users list. This action does not disable 2FA on your own account.

Enable 2FA on a user account

Important:

 You cannot enable 2FA for a user account through the WHM interface.

To enable 2FA for a user account, log in to the cPanel interface as the user and navigate to cPanel's Two-Factor Authentication interface (Home >> Security >> Two-Factor Authentication).

You can also call API functions to access 2FA functionality. For more information, read our Guide to API Authentication documentation.

  1. Click Set Up Two-Factor Authentication.
  2. To configure 2FA, you must create a link between your cPanel account and your 2FA app:

  3. Within your 2FA app, retrieve the six-digit security code.
