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 correct usage is to enter the name of the keychain item (not the name of the keychain itself, and not the "Account" field for the keychain item).

My problem was actually related to access control. I had to edit the keychain item in Keychain Access and tweak the Access Control settings to allow altool to see the keychain item.
