Implementing Sign In with Apple in your Django (Python) backend

Apple announced a new feature, "Sign In with Apple" enabling users to sign in to apps using their Apple ID. This new feature is meant to be a secure and privacy-friendly way for users to create an account in apps. Most iOS and Mac users already have an Apple ID, and this new feature lets them use that Apple ID to sign in to other apps and websites.

Apple is taking a firm stance to protect user's privacy, rather than letting applications see the user's real email address, they will provide the app with a fake or random email address unique to each app. Don't you worry! Developers will still be able to send emails to these proxy addresses, it just means developers won't be able to use the email addresses in any other way. This feature will also allow users to disable email forwarding per application.

How it works

Apple adopted the existing standards OAuth 2.0 and OpenID Connect to use as the foundation for their new API. If you're familiar
