Google Sign-In is a secure authentication system that reduces the burden of login for your users, by enabling them to sign in with their Google Account—the same account they already use with Gmail, Play, and other Google services. You can give your users the opportunity to pay with Google Pay, share with their Google-wide contacts, save a file to Drive, add an event to Calendar, and more. See some case studies of successful Google Sign-In integrations. With One Tap sign-in and sign-up for Android and web, you get frictionless sign-in and sign-up flows for your apps. Users can create new accounts on your service with a single tap and get assisted signed-in across devices. In turn, you reduce the risk of forgotten user passwords and missed conversion opportunities when users get frustrated trying to sign in or move on to another activity. Assisted sign-in lets user choose their existing account, preventing duplicate account creation and reducing the number of support cases. When a user saves their password with Google on Android or Chrome, they can skip entering their credentials on all of their devices. Google Account Linking lets users link third-party accounts to their Google account. By linking accounts, users can use Google surfaces and devices to interact with third-party services.
