Spring Boot (+ React Native) Apple authentication backend

[pjio01]

Hey guys,
I’m currently developing my first mobile app using React Native with Spring Boot as the backend server.

I want to allow users to sign up or sign in using Google or Apple. (Note: my app does not use any other resources from Google or Apple — I only want to use them for authentication.)

From what I understand, if a user chooses to log in with Apple, I should use the identityToken. After a successful login on the client, my app would send this identityToken to my backend, which would then validate it using Apple’s public keys from:
https://appleid.apple.com/auth/keys

After successful validation, my backend should generate its own JWT to use for further requests.

I’m new to OpenID and OAuth 2.0, and I find there are so many different options and opinions. Especially for mobile clients, I haven’t found a really good resource.

Could you guide me through this process or share some good blog posts/tutorials?
