YubiKey is a hardware-based two-factor authentication (2FA) device that provides an additional layer of security for accessing online platforms, including WHMCS. It generates one-time passcodes (OTP) that users must enter along with their regular login credentials. Here's how you can set up YubiKey for administrators in WHMCS:

Setting Up YubiKey for WHMCS:

1. Purchase and Set Up YubiKey:

   • Acquire YubiKey devices for each administrator who will use them for authentication.
   • Follow the manufacturer's instructions to set up the YubiKey for use with OTP.

2. Install YubiKey Plugin for WHMCS:

   • Download and install the YubiKey plugin for WHMCS from the WHMCS Marketplace or directly from the Yubico website.

3. Configure YubiKey Plugin:

   • In your WHMCS admin panel, go to "Setup" > "Addon Modules".
   • Locate the YubiKey module and click "Activate".

4. Configure API Key:

   • Obtain an API key from the Yubico website by creating a new Yubico account or logging in to your existing one.

5. Enter API Key in WHMCS:

   • In the YubiKey module settings, enter the API key provided by Yubico.

6. Set Up Users in Yubico:

   • In the Yubico admin panel, add the users who will be using YubiKey for authentication.

7. Configure User Accounts in WHMCS:

   • In WHMCS, go to "Setup" > "Staff Management" > "Administrators".
   • Edit the administrator accounts you want to enable YubiKey for.

8. Enable YubiKey for Administrators:

   • In the administrator's profile, locate the "Two-Factor Authentication" section.
   • Choose "YubiKey" and enter the Public Identity of the corresponding user in Yubico.

9. Testing YubiKey:

   • Log out of your WHMCS admin panel and log in again. You should be prompted to authenticate using YubiKey.

10. Authenticate with YubiKey:

    • Insert your YubiKey into a USB port or follow the manufacturer's instructions for the specific YubiKey model you have.

    • Press the YubiKey button to generate an OTP. The OTP will be automatically entered into the authentication prompt.

    • If successful, you will gain access to the WHMCS admin area.

Best Practices for Using YubiKey:

• Encourage 2FA Use: Encourage all administrators to use YubiKey for two-factor authentication.

• Recovery Codes: Some 2FA setups provide recovery codes. Encourage administrators to store these codes securely in case they are unable to access their 2FA device.

• Education and Training: Provide training on 2FA and its benefits to all administrators.

By setting up YubiKey with WHMCS, you add an extra layer of hardware-based security to your admin area, helping to protect sensitive information and prevent unauthorized access.
