Thanks for bringing your question to our Community forum. I’m more than happy to help out with this!
Based on the screenshot you’ve shared, it appears that you have password protection enabled on your store. The password page is a landing page that adds password protection to your online store. Once you remove the password page, anyone will be able to visit your store. Please note that you can only remove password protection from your store after you pick a pricing plan. If you’ve already done so, you can remove the password page by following these steps:
From your Shopify admin, go to Online Store > Preferences.
Go to the Password protection area.
Uncheck Enable password.
Click Save.
Please let me know if you have any questions about that! In the meantime, I’d love to hear more about your store. Is this a new business venture you’ve started?
