If you happen to have lost the 2FA for your forum account, don't worry, recovery is super simple!
If you had generated backup codes when setting up 2FA for your account, all you need to do is click on "Log in using a backup code" and enter any one of the 10 codes you have (just make sure to delete it once you've used it, as they are one-time use codes).
However, if you didn't generate backup codes when setting up 2FA, no problem! Just submit a support ticket using the same email address that's linked to your account, and we'll be more than happy to help you remove it.
