Sometimes, before going live with your store, you didn't want to show everyone your work in progress, so you protected your store with a password. We would need to see your storefront and what you have in there so we can evaluate your request. Here’s how to find your password.
Access the backend of your store, from Shopify admin, go to Online Store > Preferences.
In the Password page section, the password for the storefront will be displayed here.
