What is the best app for password-protected collections on Shopify?

Locksmith Shopify app is an excellent app for password-protected Shopify pages, collections and products. Due to its remarkable features like customer tag, products organization, content viewing limit, multiple passcodes, and subscription to Klaviyo or Mailchimp, I recommend Locksmith over any other alternative. So, use this app, and that's how to password protect the Shopify store. Easy peasy!
