Step 4: Set Up 2FA for Users

Once 2FA is enabled for a user, they will need to configure their 2FA device (usually a mobile phone) for authentication.

1. Send the User an Email or Notification:
   • The user will receive an email with instructions on how to set up 2FA via an authenticator app, such as Google Authenticator or Microsoft Authenticator.
2. User Configures 2FA:
   • The user will need to download and install an Authenticator App (like Google Authenticator) on their smartphone.
   • They should scan the QR code provided in the email or in the 3CX Web Client’s “2FA Setup” page.
   • After scanning the QR code, the app will generate a 6-digit code that the user must enter in the 3CX Web Client to complete the setup.
3. Complete Setup:
   • After entering the code from the authenticator app, the 2FA setup will be complete, and the user will be required to use this app for future logins.

Step 5: Test 2FA for Users

1. Have the user log into the 3CX Web Client or the 3CX Mobile App.
2. After entering their username and password, they should be prompted to enter a verification code generated by their authenticator app.
3. If the code is correct, the user will be logged in successfully.

Step 6: Disable or Reset 2FA (if needed)

If you need to disable or reset 2FA for any user, follow these steps:

1. Go to Extensions in the 3CX Management Console.
2. Select the user whose 2FA you want to disable or reset.
3. Under the Security section of the user’s extension settings, uncheck the Enable Two-Factor Authentication option or click Reset to remove the current 2FA configuration.
4. Save the changes.

Conclusion

With Two-Factor Authentication (2FA) enabled, 3CX users will need to use a second factor (usually a smartphone authenticator app) to log in securely. This significantly enhances the security of your system by protecting against unauthorized access, even if a user’s password is compromised.
