Apple Sign In
Apple Sign In is an authentication service provided by Apple that allows users to sign into apps and websites using their Apple ID. It offers a privacy-focused alternative to social logins, with features like private email relay and two-factor authentication. Developers can integrate it into iOS, macOS, watchOS, tvOS, and web applications to streamline user onboarding.
Developers should use Apple Sign In when building apps for Apple platforms (especially iOS/macOS) to comply with App Store guidelines that require offering it as an option for social logins. It's ideal for enhancing user privacy, reducing password fatigue, and accessing Apple's ecosystem features like Face ID/Touch ID. Use cases include consumer apps, subscription services, and any application where user authentication is needed with minimal data collection.
