iOS Question Error during upload of ipa file to iTunes Connect

How can I sign App with password?
During upload of ipa archive to iTunes Connect appear an error:
Error: 2019-03-01 09:39:07.727 altool[83056:5090500] *** Error: Unable to validate your application. 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
I can generate a password for App by appleid.apple.com. (i'm using B4i 5.3)
How can I sign App with this password?

This is for Two-factor security.
1. Go appleid.apple.com
2. Choose the password for App and insert the same in iTunes Connect Uploader ( see picture here )
