What does the error to sign in with an app-specific password in Transporter mean?

- Your Apple ID is enabled for two-step verification, and you'll need to generate an app-specific password at appleid.apple.com. After you set that password, you'll have to use it whenever you sign in to Transporter.
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)
