The password page in a Shopify theme is a page that is only accessible to visitors who know the password. This can be used to protect certain areas of your store, such as a members-only area or a preview of a new product.
To create a password page in Shopify, you first need to enable password protection in your store's preferences. You can do this by going to Online Store > Preferences > Password Protection and checking the box next to Restrict access to visitors with the password.
Take the following steps:
In the theme editor (Customize), click on the page selector
Go to the Others > password
