Hi there, @bryan76 . Thanks for taking the time to reach out to the Shopify Community Forums with your question. My name is Imogen. It’s good to meet you.
If you’re wanting require customer accounts, then you won’t be able to offer a way for customers to use ‘guest checkout’, as you’re removing the ability to checkout without logging into an account with specific information attached. Editing the checkout page itself is also not possible, as this code is locked down pretty tightly for security purposes. If you’re looking to provide a way for customers to quickly create an account without completing the typical required steps, you’ll need some help from a third party like a Shopify Expert to achieve this.
