Two-factor authentication (2FA) is an extra layer of security, used to make sure that people trying to gain access to an online account are who they say they are. It requires the user to first enter their username and password, then they are required to provide a second piece of information, usually from a separate device like a smartphone or tablet, to confirm their identity. This means that if someone’s password is compromised, the chances of someone else having the second-factor information is highly unlikely.
Once you are set up for two-factor authentication, you are asked to enter a six-digit verification code when logging in. If you enter this incorrectly, an error message will appear.
The most common reason for this error message would be that your date and time is not synchronised on your smartphone or tablet. This setting is amendable in your devices settings area, usually under 'date and time'. You must ensure 'Automatic date and time' is toggled on for your device.
If you are still experiencing this error message after troubleshooting, please raise a case with the support team.
