|Feature||Publish to iTunes Connect|
When using AppBuilder to publish an iOS app to iTunes Connect, the publish procedure fails with an error message about an app-specific password.
Sign in with the app-specific password you generated. If you forgot the app-specific password or need to create a new one, go to appleid.apple.com (-22938)
Please sign in with an app-specific password. You can create one at appleid.apple.com. (-22910)
These errors mean that you have enabled two-step verification or two-factor authentication for your Apple ID. With these feaures enabled, iTunes Connect requires an app-specific password when you use services that do not support entering a verification code, such as AppBuilder.
Create an app-specific password in your Apple ID account page and use it when logging into iTunes Connect from AppBuilder. Instructions for generating an app-specfic password are available in this article.
