Why do I see the "Invalid verification code" error when setting up 2FA?

An "Invalid verification code" error in the VT Markets Client Portal typically occurs when your 6-digit one-time password (OTP) expires before submission, your mobile device clock is out of sync with global server time, or you enter a code from an outdated authenticator entry. You can resolve this error immediately by verifying your active authenticator entry and synchronizing your device's time settings.

What do you need to check before retrying your 2FA code

Two-Factor Authentication (2FA) apps generate time-based security codes that rely on exact timestamp matching between your mobile device and VT Markets' security servers. Check these two common issues first:

  • The 6-digit code in Google Authenticator or Microsoft Authenticator refreshes every 30 seconds. Wait for a fresh code to appear if the timer is about to run out, and enter all 6 digits without spaces.

  • If you previously set up 2FA and see multiple VT Markets entries inside your authenticator app, ensure you are reading the code from your most recent active binding and remove any expired entries to avoid confusion.

Steps to synchronize your device time for 2FA

If your 2FA codes still fail, calibrate your mobile device clock using the steps for your operating system below:

  • On iOS devices (iPhone / iPad)

  1. Open your device Settings and tap General.

  2. Select Date & Time.

  3. Toggle Set Automatically to ON so your device syncs directly with network time.

  4. Return to your authenticator app, wait for a new 6-digit code to generate, and retry logging in. (If the error persists due to local carrier drift, test temporarily adjusting your time zone offset by UTC±1 before switching back to automatic.)

  • On Android devices

  1. Open the Google Authenticator app and tap the Menu icon (three horizontal lines) in the top-left corner.

  2. Select Settings.

  3. Tap Time correction for codes.

  4. Tap Sync now to calibrate the app's internal clock with Google's time servers, then try your new code.


 

What if the 2FA code still fails after syncing your mobile device clock

  1. Clear your web browser's cache and cookies, or open an incognito/private browsing window before logging in to the VT Markets Client Portal to eliminate stale session tokens. 
  2. Ensure your computer's system clock is also set to update automatically.
  3. See another article"How do I reset and enable 2FA?" to reset your 2FA.
