Hey there, @david24365
Bo here from Shopify Support!
Great question. If you contact our support team directly they should be able to grant you temporary access to your account so that you can transfer your domain to another host. Visit the Shopify Help Center to contact the support team. As you are unable to log in to your account currently, please select the option to continue without logging in here.
Please note that domains can only be transferred to another host after 60 days have passed, domains bought less than 60 days ago cannot be transferred. Once you have access to your account you can follow these steps to transfer your domain away from Shopify.
Best of Luck,
