I am not receiving my TFA code


  • I am trying to log in to my Unity ID but I'm not receiving my Two Factor Authentication (TFA) code.
  • I am experiencing a delay in TFA codes and I don't know why.
  • I am unable to retrieve my TFA code as it is going to an old device.


There are a number of reasons why there could be a delay in receiving your code. Here are some examples.

  • What causes this varies from handset to handset. If a mobile device is located outside a network's coverage area or in a spot where the network signal is blocked such as in a mountainous region, a delay in transmission may occur. In urban areas, tall buildings can also cause transmission issues. Being in an old building with poor cell phone reception is another possible culprit.
  • The most obvious cause is a device that has been turned off, but a weak or uncharged battery may also negatively impact message delivery. 
  • A text sender and receiver using different networks may have a greater chance of experiencing texting delays than those using the same network, because of communication between networks, or the carrier prioritizing their own traffic.
  • Texting during periods of heavy network use impacts text delivery speed. Periods of increased traffic may create congestion on the local network and delay the arrival of messages to the handset.


Whilst there are a number of reasons which could be delaying the message, this is out of our control.
You can only combat this by making sure your device is charged sufficiently.

More Information:

TFA is not to be confused with the Security Notification Codes which are sent via email when our system flags a login attempt as risky. More information on this can be found in the article ‘I have been asked to enter a verification code while trying to log in. Why did I receive this?’.
