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, 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 Google 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.

See some case studies of successful Google Sign-In integrations.

One Tap sign-in and sign-up

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.

Firebase Authentication

Firebase Authentication makes building secure authentication easy, providing sign-in and on-boarding for your users on all their devices.

It provides backend services to securely authenticate users, paired with easy-to-use client SDKs. It can authenticate users using passwords and federated identity provider credentials.

Firebase Authentication also provides UI libraries to implement a full authentication experience in your app.

Google Account Linking

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. Google Account Linking enables users to quickly, seamlessly, and securely connect to third-party services with their Google identity.

Using the secure OAuth 2.0 protocol a Google user account may safely be linked to a user account on your platform, thereby granting Google users and applications access to your services.

Users may link or unlink their accounts, and optionally create a user account on your platform using Google Account Linking.

SMS Retriever API

Verify your users by SMS without making them deal with verification codes. By using the SMS Retriever API, your Android app can automatically retrieve verification codes intended for your app, without having to request full SMS reading permissions.
