Two-Factor Authentication for WHM Print this Article
Overview:
This function allows you to configure two-factor authentication (2FA), a security measure for the login interface of cPanel & WHM. Two-factor authentication requires two forms of identification. After you enter your password, you must enter a security code. An application on your smartphone supplies this code. Without your smartphone, you cannot log in.
For more information about 2FA, read Wikipedia’s Two-Factor Authentication article.
-
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
ntpdatecommand 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.
-
-
2FA supports only one concurrent session for any user. If you open several browser windows to cPanel & WHM and log out in one of them, the server will log out the other windows.
2FA requires a smartphone with a supported time-based one-time password (TOTP) app. We suggest the following apps:
-
For Android™, iOS®, and Blackberry® — Google Authenticator™
-
For Android and iOS — Duo Mobile
-
For Windows® Phone — Authenticator
Enable 2FA
If 2FA is disabled on the server, set the toggle to On to enable 2FA.
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.
To set the Issuer setting for 2FA, perform the following steps:
-
Click the Settings tab.
-
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. -
Click Save.
Manage Users
The Manage Users tab displays the accounts for which you have configured 2FA. It also 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:
-
Select the Manage Users tab.
-
Select the checkboxes to the left of each user account that you want to remove. To select all accounts, select the checkbox to the left of the User heading.
-
Click the gear icon
on the top right of the list, and then select Disable Selected.
Select Disable All to remove every user account from the Manage Users list. This will not disable 2FA on your own account.
Enable 2FA on a user account
You cannot enable 2FA for a cPanel account through the WHM interface. You must enable the Two-Factor Authentication Security Policy on the server in order to enable 2FA for cPanel accounts.
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 (cPanel >> 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.
