Sign in with Apple JS

Provide users a fast, secure way to sign into your web service with their Apple ID.


Sign in with Apple is the fastest way to onboard new users securely and provides two-factor authentication. Using Sign in with Apple JS, you can allow users to log into your website with their Apple ID, rather than creating a new account and password.

Enabling Sign in with Apple for your app begins with registering your app in your Apple Developer account. When integrating the API with your app, consider button presentation style, notification options, server integration, and what kind of user information to request.

To communicate between your server and Apple servers, use Sign in with Apple REST API. Alternatively, to let users set up accounts and sign in to your native iOS, macOS, tvOS, and watchOS apps, use the AuthenticationServices framework.
