Identity tools from Google help you quickly build an auth system that will grow with your business and reduce the friction of getting users into your app.

Google Sign-In

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.

Google Sign-In is also your gateway to connecting with Google’s users and services in a secure manner. You can give your users the opportunity to pay with Android Pay, 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.

Smart Lock for Passwords

With Smart Lock for Passwords, you get frictionless sign-in and sign-up into apps on Android and sites in Chrome with any account. Users will get automatically 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.

Once your user saves a password to Smart Lock, they can skip entering their credentials on all of their Chrome and Android devices.

Identity Toolkit

Identity Toolkit gives you a robust, secure authentication system in a box that helps you do sign-in the right way, no matter what account your users want to use.

The toolkit gives you password authentication, in addition to federated sign-in with major identity providers (Google, Facebook, and more). We’ve done the heavy lifting of building a secure auth solution that can grow with your app. Even non-technical developers are able to add future sign-in options and migrate existing users with simple configuration changes.

Use this to easily scale your auth system as you grow on desktop and mobile.

Identity Platform for Work

Google’s SAML and OpenID Connect support can be used with Google Apps for Work. There are multiple approaches that can be used based on the type of app, and the platform the app runs on.
