# Authentication StateAPI

The API for interacting with authentication state.

## OrderStatusApi

The API object provided to this and other `customer-account.order-status` extension targets.

* authenticationState

  SubscribableSignalLike\<AuthenticationState>

  required

  The authentication state of Order status page.

### SubscribableSignalLike

Represents a read-only value managed on the main thread that an extension can subscribe to. Example: Checkout uses this to manage the state of an object and communicate state changes to extensions running in a sandboxed web worker. This interface is compatible with \[Preact's ReadonlySignal]\(https\://github.com/preactjs/signals/blob/a023a132a81bd4ba4a0bebb8cbbeffbd8c8bbafc/packages/core/src/index.ts#L700-L709). Some fields are deprecated but still supported for backwards compatibility. In version 2025-10, \[\`StatefulRemoteSubscribable\`]\(https\://github.com/Shopify/remote-dom/blob/03929aa8418a89d41d294005f219837582718df8/packages/async-subscription/src/types.ts#L17) was replaced with \`ReadonlySignalLike\`. Checkout will remove the old fields some time in the future.

* current

  ```ts
  T
  ```

* destroy

  ```ts
  () => Promise<void>
  ```

* subscribe

  ```ts
  (fn: (value: T) => void) => () => void
  ```

* value

  ```ts
  T
  ```

```ts
export interface SubscribableSignalLike<T> extends ReadonlySignalLike<T> {
  /**
   * @deprecated Use `.value` instead.
   */
  readonly current: T;
  /**
   * @deprecated No longer needed. Use Preact Signal management instead.
   */
  destroy(): Promise<void>;
}
```

### AuthenticationState

```ts
'fully_authenticated' | 'pre_authenticated'
```
