Module: Wokku::Auth

Defined in:
lib/wokku/auth.rb

Overview

Authentication flows for ‘wokku auth:login`.

CLI requests a device_code + user_code from /auth/device/code, opens the verification URL in the browser, and polls /auth/device/token until the user approves the session in the dashboard. Server returns an api_token which the CLI persists to ~/.wokku/config.
