Shopify CLI 3.83.x and older lose support for password-protected theme development on October 1

Shopify’s official Developer Changelog says that, starting October 1, 2026, Theme commands for password-protected storefronts will require Shopify CLI 3.84.0 or later.

CLI versions 3.83.x and earlier will no longer be supported for theme-development workflows on password-protected storefronts.

The named workflows include shopify theme dev, shopify theme console, and shopify app dev when the app uses theme app extensions.

Shopify recommends upgrading to the latest available CLI version and checking the installed version with shopify version; the supplied changelog identifies 4.7.0 as its recommendation at publication.
