Facebook Login
Facebook Login is an authentication service provided by Meta (formerly Facebook) that allows users to sign into third-party applications using their Facebook credentials. It simplifies the login process for users by eliminating the need to create new accounts, while providing developers with access to user profile data and permissions. The service is commonly integrated into web, mobile, and desktop applications to enable social login functionality.
Developers should use Facebook Login when building applications that require user authentication and want to leverage Facebook's large user base for easier onboarding. It is particularly useful for social apps, e-commerce platforms, and services that benefit from accessing user data like profile information or friend lists. This reduces friction for users and can increase sign-up rates compared to traditional email/password registration.
