Get started

If you don't know the concept of the connector or don't know how to add this connector to your Sign-in experience, please see Logto tutorial.

ℹ️ Note

Apple sign-in is required for AppStore if you have other social sign-in methods in your app. Having Apple sign-in on Android devices is great if you also provide an Android app.

You need to enroll Apple Developer Program before continuing.

Enable Sign in with Apple for your app

⚠️ Caution

Even if you want to implement Sign in with Apple on a web app only, you still need to have an existing app that embraces the AppStore ecosystem (i.e., have a valid App ID).

You can do it via Xcode -> Project settings -> Signing & Capabilities, or visit Certificates, Identifiers & Profiles.

See the "Enable an App ID" section in Apple official docs for more info.

Create an identifier

1. Visit Certificates, Identifiers & Profiles, then click the "+" button next to "Identifier".
2. In the "Register a new identifier" page, choose "Services IDs" and click "Continue".
3. Fill out "Description" and "Identifier" (E.g., Logto Test and io.logto.test), then click "Continue".
4. Double-check the info and click "Register".

Enable Sign in with Apple for your identifier

Click the identifier you just created. Check "Sign in with Apple" on the details page and click "Configure".

In the opening modal, select the App ID you just enabled Sign in with Apple.

Enter the domain of your Logto instance without protocol and port, e.g., your.logto.domain; then enter the "Return URL" (i.e., Redirect URI), which is the Logto URL with /callback/${connector_id}, e.g., https://your.logto.domain/callback/apple-universal. You can get the randomly generated connector_id after creating Apple connector in Admin Console.

Click "Next" then "Done" to close the modal. Click "Continue" on the top-right corner, then click "Save" to save your configuration.

⚠️ Caution

Apple does NOT allow Return URLs with HTTP protocol and localhost domain.

If you want to test locally, you need to edit /etc/hosts file to map localhost to a custom domain and set up a local HTTPS environment. mkcert can help you for setting up local HTTPS.

ℹ️ Note

This connector doesn't support customizing scope (e.g., name, email) yet since Apple requires form_post response mode when scope is not empty, which is incompatible with the current connector design.

We'll figure out this later.

Test Apple connector

That's it. The Apple connector should be available in both web and native apps. Don't forget to Enable connector in sign-in experience.
