If the system repeatedly displays an "Invalid verification code" error while you are trying to enable Two-Factor Authentication (2FA), follow the troubleshooting steps below:

1. Verify the 2FA OTP Code: Ensure you are entering the active verification code from your Google Authenticator or Microsoft Authenticator app. Authenticator codes refresh every 30 seconds, so enter the latest code before the countdown expires.
2. Refresh or Use Incognito Mode: Refresh your browser page or attempt the binding process using an incognito/private browsing window.
3. Rebind 2FA for Unverified Status: If you exited during setup or encountered network delays causing the "Security Authenticator app" status to display as Unverified, follow these steps to reset the binding:
Remove any previously added VT Markets accounts from your authenticator app to avoid entering outdated codes.
In the Client Portal, scan the latest QR code with your authenticator app.
Enter the current 6-digit code shown in your authenticator app to successfully complete the 2FA activation.
