Sign In with Google SDKs
Users signed into Google on their device or browser get expedited authentication on your app or site.
Returning users sign in automatically or with one tap or click.
You even have the option to let users create new accounts with a single tap or click.
Open-source and industry-standard authentication.
Passkeys are a safer and easier replacement for passwords.
Google's OAuth 2.0 APIs conform to the OpenID Connect specification, are OpenID Certified, and can be used for both authentication and authorization.
These APIs are listed here for historical reference.
Share data with Google apps and devices
Integrate your services and APIs with Google, share media and data with Google Assistant, Smart Home, YouTube and more. After obtaining user consent securely link an individual Google account with an account on your platform with OAuth 2.0 standard flows.
Improve user privacy with custom scopes, sharing only the data necessary for a specific use case. Increase user trust by clearly communicating how Google uses this data.

Announcing the Federated Credential Management (FedCM) Beta for Google Identity Services.
GIS currently uses third-party cookies to enable users to easily sign up and sign in to websites, making sign-in more secure for users by reducing reliance on passwords. However, as part of the Privacy Sandbox initiative, Chrome is phasing out support for third-party cookies in 2024 to protect user privacy online.
Google Identity Services (GIS) is making authentication safer and easier for developers with new features recently added across our libraries:
- Verified Phone Number and Phone Number Hint on Android
- One Tap for Web on Intelligent Tracking Prevention (ITP) browsers
- Google Sign-In for iOS now supports macOS, as well
We've made our OAuth implementation more safe and secure, deprecating support for out-of-band (OOB) flows and Loopback IP address flows to reduce the risk of phishing and app impersonation attacks during OAuth interactions.
