How should the keychain option be used for altool?

Question

I\'m trying to use the @keychain option with the -p switch in altool in order to load my iTunes Connect password from the keychain:

Answer 1

The way that worked for me was logging in with the Application Loader itself (check the "Keep me logged in" option) and use the keychain entry of the Application Loader.

So my command looks like this:

altool --validate-app -f APPLICATION.ipa -u my@apple.id -p @keychain:"Application Loader: my@apple.id"
