Using Two-Factor Authentication (2FA) in WHMCS adds an extra layer of security to your admin area. Here's how you can use 2FA in WHMCS:

1. Enabling Two-Factor Authentication:

   • Log into WHMCS as an administrator.
   • Navigate to "Setup" > "General Settings" > "Security".
   • Check the box labeled "Enable Two-Factor Authentication for Administrators".
   • Select your preferred 2FA method (e.g., Google Authenticator, YubiKey, etc.).
   • Save the changes.

2. Setting Up 2FA for Administrators:

   • Go to "Setup" > "Staff Management" > "Administrators".
   • Edit the administrator accounts you want to enable 2FA for.
   • In the administrator's profile, locate the "Two-Factor Authentication" section.
   • Choose your 2FA method and follow the setup instructions.

3. Logging In with 2FA:

   • When an administrator logs in, they will first enter their username and password.
   • They will then be prompted to provide the second authentication factor, depending on the chosen 2FA method.

4. Using Google Authenticator for 2FA:

   • If you selected Google Authenticator as your 2FA method, you'll need to set it up on your mobile device:
     • Download and install the Google Authenticator app.
     • Scan the QR code displayed in WHMCS using the app.
     • Enter the generated code to complete the setup.

5. Using YubiKey for 2FA:

   • If you selected YubiKey as your 2FA method, follow the manufacturer's instructions to set up your YubiKey for use with WHMCS.

6. Using Other 2FA Methods:

   • Depending on the chosen 2FA method (e.g., SMS, email, hardware token, etc.), follow the specific instructions provided.

7. Storing Recovery Codes (if provided):

   • Some 2FA setups provide recovery codes. Store these codes securely in case you are unable to access your 2FA device.

8. Regular Use of 2FA:

   • Encourage all administrators to use 2FA for their accounts.

Best Practices for Using 2FA:

• Regular Auditing: Periodically review and audit administrator accounts and their 2FA status to ensure compliance with security policies.

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

• Recovery Codes: Some 2FA setups provide recovery codes. Store these codes securely in case you are unable to access your 2FA device.

• Strong Passwords: Continue to use strong passwords in conjunction with 2FA.

By using Two-Factor Authentication in WHMCS, you add an extra layer of security to your admin area, helping to protect sensitive information and prevent unauthorized access.
