This plugin integrates the Sign In with Apple service into CMS platforms, allowing users to log in using their Apple ID. It is designed for site administrators who want to offer a trusted, alternative login method, particularly for existing user bases.

• Apple ID Integration: Adds a 'Sign In with Apple' button to the standard CMS login page, providing users with a familiar and secure authentication option.
• Existing User Association: Focuses on allowing current CMS users to link their existing accounts to their Apple ID, streamlining future logins without creating duplicate accounts.
• Secure Token Validation: Utilizes JSON Web Token (JWT) validation based on Apple's public keys to ensure the authentication responses are legitimate and secure.
• Developer Installation: Requires installation via Composer due to its use of a third-party package for JWT parsing, ensuring proper dependency management.
• Configuration via Admin: Setup involves specifying your Apple Service ID in the site's options panel and associating user accounts through the profile management page.
