Apple Sign-in

Apple Sign-in is not an advertising product or company. It is a user authentication system that allows users to sign in to apps and websites using their Apple ID. This system provides an alternative to signing in with other social media accounts like Google or Facebook. Apple Sign-in emphasizes user privacy by not sharing user data with developers unless explicitly permitted. Users can also choose to hide their email address from developers and use a unique, randomly generated email address for each app. This system is intended to provide a more secure and private way for users to access online services.
