The new Shopify site (http://shop.selectblinds.com) does not use passwords. Instead, it uses an email and a unique 6-digit one-time passcode to log in. Here's how it works:
Go to http://shop.selectblinds.com and click the person icon in the upper-right corner to be directed to the “Sign In” page for your account.
Enter your email address.
Check your email inbox for a one-time passcode from SelectBlinds.
Enter the code to access your account.
