Get people into your apps quickly and securely (we'll even help them install the app!)
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, Google+, and other Google services.
Create a seamless experience across screens for your users
Your users expect a seamless experience with your app and site, regardless of what device they use. Integrating Google sign-in means your users grant consent once, then continue their experience of your app and website in a secure manner. In turn, you get the opportunity to create a seamless experience for someone across your properties, no matter what device they’re picking up.
Tap into Google’s services to help your users take action
Google sign-in is your gateway to connecting with Google’s users and services in a secure manner. You can give your users the opportunity to pay with Google Wallet, share with their Google-wide contacts, save a file to Drive, add an event to Calendar, and more. Integrate Google’s user-centric APIs and services inside your app to help your users take action and convert.
