Troubleshooting two factor authentication
If you can't get into Trello because you're not receiving the SMS with your code, these steps can help you get back into your account.
Using your backup codes
When enabling two factor authentication (2FA), you're prompted to save or print a set of backup codes, which you can use to get back into your account if you don't currently have access to your second device. You can use one of those codes in the two factor authentication code field in the login screen, instead of the code you would normally receive via SMS or from your authentication app.
Backup codes are the best and primary method of regaining access to your account
Use a backup code to log into your 2FA-enabled Trello account.
After you're logged in, you can disable 2FA by going to https://trello.com/2fa and clicking on the 'Disable Two Factor Authentication' button:
Disable 2FA with one of your backup codes.

If you're not able to get into your account using these methods, contact our support team for additional help. While we won't disable 2FA on an account or change the phone number for security reasons, we can help users who haven't changed phone numbers but have stopped receiving messages for other reasons.
