Google Sign-In
Google Sign-In is an authentication service provided by Google that allows users to sign into third-party applications using their Google account credentials. It simplifies the login process by eliminating the need for users to create new accounts and passwords, while providing developers with secure access to user profile information and OAuth 2.0 tokens for Google APIs. This service is widely used in web, mobile, and desktop applications to enhance user experience and streamline authentication workflows.
Developers should use Google Sign-In when building applications that require user authentication, especially to reduce friction for users who already have Google accounts and to leverage Google's security infrastructure. It is particularly valuable for applications that need to access Google services like Gmail, Google Drive, or YouTube, as it provides seamless integration and authorization. Common use cases include social media apps, e-commerce platforms, and productivity tools where quick and secure login is essential.
