I understand that you’re looking to make a few customizations to the password page. Since you’re using the Dawn theme, then our Theme Support can assist you with some of these tasks. However, in order to be eligible for the complimentary design time included with our design policy, your store will need to be subscribed to a monthly plan. While we’re unable to provide account-specific support via the Shopify Community, we’d be happy to assist you with a customization request through live chats. Simply visit the Shopify Help Center and login to your account to create a support request.
That being said, while our Theme Support team can help you in exploring solutions for these customizations, some of them may not be supported. For these types of unsupported customizations, we’d encourage to consider hiring a developer to further assist you. If you need help finding a developer for your store, then we’d recommend taking a look at our directory of certified developers on Shopify Partners.
I noticed that you’re a new member of our Shopify Community! Once you’ve submitted the customization request, I’d love to hear more about your business and share some resources to help you get started. What types of products are you looking to sell? Do you have a marketing plan prepared for your store?
