Invalid Google Authenticator Passcode

If the portal shows the six-digit Google Authenticator passcode as invalid, it could be because the passcode is near expiration.

The passcode in Google Authenticator is time-based and changes every 30 seconds. Make sure that you enter the passcode when the numbers are blue, and not red. If the numbers are red, wait a few seconds until a new passcode appears in blue, and then enter the passcode.
