What is instagram backup code not working?

As an AI language model, I do not have access to current technical issues or troubleshooting steps for Instagram backup codes. However, in general, if you are experiencing issues with your Instagram backup code not working, you may want to try some of the following troubleshooting steps:

1. Make sure you have the correct code: Ensure that you are entering the correct backup code that you were given when you set up two-factor authentication on Instagram.

2. Check if your phone number has changed: If you have changed your phone number or SIM card, your backup codes might have changed, as well. Make sure to update your phone number in your Instagram settings.

3. Reset your two-factor authentication: If none of the above solutions work, you may want to try resetting your two-factor authentication on Instagram. This will assist you in obtaining a new set of backup codes.

If your backup codes aren't working, you can attempt to authenticate via your phone number or via a third-party authentication verification app instead of using codes.
