You should receive your Installer passcode on the day of your installation. The 3rd-party installer responsible for your installation will send you your installer passcode once the installation has been completed. Once you have entered your Installer passcode, you will be prompted to update your password to log in to your Emerald Home App.
Your installer passcode is a one-time use-only code allowing you to access your account on the installation day. Your Installer passcode is randomly generated and is not stored by Emerald. You will not need to use your Installer passcode to log in once it is completed the first time.
You won't be able to present your Installer code to log into your Emerald Home App.
