	help: '''
		Use this command to login to your resin.io account.

		This command will open your web browser and prompt you to authorize the CLI
		from the dashboard.

		If you don't have access to a web browser (e.g: running in a headless server),
		you can fetch your authentication token from the preferences page and pass
		the token option.

		Alternatively, you can pass the `--credentials` boolean option to perform
		a credential-based authentication, with optional `--email` and `--password`
		options to avoid interactive behaviour (unless you have 2FA enabled).

		Examples:

			$ resin login
			$ resin login --token "..."
			$ resin login --credentials
			$ resin login --credentials --email johndoe@gmail.com --password secret
