Users may experience delays or failure in receiving Unity ID Two Factor Authentication (TFA) codes due to poor reception, airplane mode, network differences, or heavy traffic. If access to the linked device is lost, users can contact Customer Experience with private and public information to deactivate TFA temporarily. Using an authenticator app is recommended for better security and code availability. For Unity Ads Tipalti TFA issues, contact Unity Ads Support.
In April 2026, we introduced an account security update that enforces two-factor authentication (2FA) for users who have enabled it.
With this update:
- 2FA is now required at every login
- Security checks are stronger for new devices and networks
- A “Remember this device for 30 days” option is available to reduce repeated prompts on trusted devices
If you no longer have access to your authentication method, you may need to complete a 2FA recovery process to regain access to your account.
Symptoms:
I am trying to log in to my Unity ID but 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.
Cause:
There are several reasons why there could be a delay in receiving your code. Here are some examples.
Poor cell phone reception.
Airplane/ do not disturb mode is switched on.
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 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.
Resolution:
| Note: For problems with TFA for your Unity Ads Tipalti profile, contact Unity Ads Support. |
If you do not have access to the device linked to your account or do not receive your TFA code as expected, contact the Customer Experience team with one piece of private information and one piece of public information to confirm your identity if you want to temporarily disable any TFA settings on your account.
Examples of private information include:
- Name your Unity organization. (Please note that a default organization is created when a Unity account is set up. Please send us the name of this or any other organization that you are part of.)
- Name of a recent Asset Store purchase.
- Recent Asset Store purchase invoice or order number.
- Name of one of your Unity Cloud projects.
Examples of public information include:
- Telephone number currently associated with your Unity ID account.
- Unity Username. (Please note that this is not your email address.)
- Full physical postal address.
If the error message "We have encountered an issue during this login attempt" appears, please refer to the article titled: I see the error, 'We have encountered an issue during this login attempt. Please contact Unity Support'.
We always recommend enabling TFA using an Authenticator app, which has a distinct advantage in terms of security and availability since authenticator apps generate local codes.
Opting for an authenticator app that backs up account information is also a good idea if you lose your phone or it's stolen or broken.
