When attempting to login to your investor portal, if you are prompted to verify token, that indicates that you have previously set-up two-factor authentication (2fa) for your account.
When you're presented with the verify token field, you'll need to open whatever authenticator app you used to scan the QR code. The app will have stored on your mobile device. For example, my phone uses the Google Authenticator App.
Once opened, find the InvestNext, investnext.com, or (sponsor name).investnext.com button in your authenticator app. Your authenticator app will continuously generate a new token every 30 seconds. Simply enter the code you see on your cell phone screen.
