Starting October 1, 2026, Theme commands on Shopify CLI for password protected storefronts will require version 3.84.0 or later. Versions 3.83.x and earlier will no longer be supported for theme development workflows on password protected storefronts.
If you use Theme commands on Shopify CLI to develop or preview themes, upgrade to the latest version before October 1, 2026. Alternatively, you can remove the password protection on your storefront to continue using your preferred CLI version.
What's changing
Older Shopify CLI versions use a legacy storefront authentication. After October 1, 2026, this legacy authentication implementation will no longer be supported for theme development flows. This impacts only password protected stores. Developers using these versions for developing password protected storefronts may need to upgrade before they can continue using commands such as shopify theme dev.
