CredentialsManager is used by most components in the fastlane.tools toolchain.

All code related to your username and password can be found here: password_manager.rb

By default, your Apple credentials are stored in the OS X Keychain.

Your password is only stored locally on your computer.

You can easily delete the stored password by opening the "Keychain Access" app, switching to All Items, and searching for "deliver". Select the item you want to change and delete it. Next time running one of the tools, you'll be asked for the new password.

FASTLANE_USER
FASTLANE_PASSWORD

If you don't want to have your password stored in the Keychain use FASTLANE_DONT_STORE_PASSWORD.

All fastlane tools are Ruby-based, and you can take a look at the source code to easily implement your own authentication solution.

require 'credentials_manager'

data = CredentialsManager::AccountManager.new(user: user, password: password)
puts data.user
puts data.password
