# Turn on Sign in with Apple in Firebase Authentication

The step `firebase_auth.apple_provider`, for [`firebase_auth`](https://doc.saymyframe.com/modules/firebase-auth.md).

The app lets users sign in with Apple through Firebase Authentication. No command can turn Apple on there, so you do it once in the Firebase console. Until then, a sign-in with Apple fails with the reason `notConfigured`, and the message for the developer says what to enable.

The iOS app also needs **Sign In with Apple** on its App ID, which signing the app in Xcode with a paid team gives it; see [the step about the App ID](https://doc.saymyframe.com/setup/app-entry-ios-app-id.md).

:::

**1. Open Authentication.** In the [Firebase console](https://console.firebase.google.com/), open your project and click **Authentication** in the menu on the left (1). If it is not among the shortcuts there, it is under **Security**. Open the tab **Sign-in method** (2). If the page offers **Get started** instead, click it first: Authentication was never set up in this project.

**2. Add Apple.** Click **Add new provider** (3).

Under **Additional providers**, click **Apple** (4).

**3. Enable it.** Turn on **Enable** (1) and click **Save** (2). An iOS app needs nothing else here: leave **Services ID** empty for now. The step about deleting accounts fills it in.

**Check.** Apple is in the list of providers with the status **Enabled**. Sign in with Apple in the app on an iPhone or a simulator with an Apple Account. On a simulator, sign in to the Apple Account in the Settings app of the simulator first.
