2-Factor Authentication is a security feature offered in App Store Connect that provides an extra layer of security for your account.

When you connect your account, we'll perform 2FA validation which will allow us to sync automatically for 30 days.

Potential Errors

Due to the nature of the 2FA process, if you start validation but don't complete it, the next validation won't be able to start up right away. This is done for security reasons.

If you see a notification that 2FA verification is already running when trying to update a linked App Store Connect account it means that you'll need to wait a few minutes before you can start it again or reach out to support who can help clear the wait.
