CredentialsManager is used by most components in the toolchain.

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


Along with the Ruby libraries you can use the command line interface to add credentials to the keychain.

Adding Credentials

fastlane fastlane-credentials add --username
Password: *********
Credential********* added to keychain.

Removing Credentials

fastlane fastlane-credentials remove --username
password has been deleted.

Storing in the keychain

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

Your password is only stored locally on your computer.

Change Password

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.

Using environment variables

Pass the user credentials via the following environment variables:


If you don't want to have your password stored in the Keychain set the FASTLANE_DONT_STORE_PASSWORD environment variable to "1".

Implementing a custom solution

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 = user, password: password)
puts data.user
puts data.password
