# Password Protected Shop Dev flows on Shopify Theme CLI v3.83.x and older to be deprecated

DateAugust 27, 2026

Flags[Deprecation announcement](https://shopify.dev/changelog?filter=deprecation-announcement)[Action required](https://shopify.dev/changelog?action_required=true)

SurfacesThemes

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`.

### What you need to do

Upgrade Shopify CLI to the latest version:

```shell
npm install -g @shopify/cli@latest
```

Then confirm your version:

```shell
shopify version
```

You should be on version **3.84.0 or later**. We recommend using the latest available version, **4.7.0**. Please follow the [documentation](https://shopify.dev/docs/storefronts/themes/tools/cli) if you are not using npm.

### Who's affected

Developers who use Theme CLI commands on versions **3.83.x and earlier** to develop password protected stores.

The most likely affected workflows are:

* `shopify theme dev`
* `shopify theme console`
* `shopify app dev` if the app has theme app extensions

### Deprecation timeline

* **October 1, 2026**:
  * Shopify will stop supporting storefront preview/session authentication from Shopify CLI versions **3.83.x and earlier**.
