If the system repeatedly displays an "Invalid verification code" error when entering your 2FA code, please follow the troubleshooting steps below:
- Verify the 2FA OTP Code: Ensure you are entering the active code from your Google Authenticator or Microsoft Authenticator app. Authenticator codes refresh every 30 seconds, so make sure to enter the most recent code before it expires.
- Synchronize Device Time (iOS): Go to your phone settings and ensure the date and time are set to Set Automatically. If the issue persists, try setting the time zone manually to (UTC±1).
- Synchronize Device Time (Android): Open the Google Authenticator app, go to Settings > Time correction for codes, and tap Sync now to align the code generation timestamp.
- Refresh or Use Incognito Mode: Refresh your browser page or attempt the login using an incognito/private browsing window.
- Clear Browser Data: Clear your browser's cache and cookies, then try logging in again.
- Switch to the VT Markets App: If logging in via a web browser fails, try signing in through the VT Markets mobile app.
If the steps above do not resolve the issue, or if you have recently changed or reset your mobile device, reset your Two-Factor Authentication by following the instructions in our guide: How do I reset my security authenticator (2FA) if I lose access?
