Sign In with Apple

iOS mobile apps must display Sign In with Apple if they already use other social providers (Facebook login, Google connect, and so on).

Even if it’s mandatory only for your iOS App using Facebook and/or Google connect, we highly recommend to push the "Sign In with Apple" option also on your websites to offer a consistent authentication experience to your customers.

Default values for Apple

The default public profile values for Apple are:

  • name

  • email

To use Sign In with Apple, you will need an App ID, a Service ID, and a Key.
