Google OAuth 2.0 (Open Authorization 2.0) is a secure authentication and authorization framework provided by Google that allows users to grant third-party applications limited access to their Google account resources without sharing their credentials (like passwords). It is widely used to enable the “Sign in with Google” functionality or to access Google APIs such as Gmail, Google Drive, and Google Calendar.
Key Features
- Authentication: Verifies a user’s identity via their Google account.
- Authorization: Grants third-party apps specific permissions to access resources (e.g., read emails, view calendar events).
- Token-Based Access: This method uses tokens (access tokens and refresh tokens) to enable secure communication between applications and Google services.
How It Works
- App Registration: The developer registers their app with Google via the Google Cloud Console, specifying the app’s name, authorized redirect URIs, and other settings.
- User Consent Flow:
- The user is redirected to a Google-hosted consent screen.
- They log in (if not already logged in) and grant the requested permissions.
- Authorization Code: After the user consents, Google sends an authorization code to the app.
- Access Token: The app exchanges the authorization code for an access token (and optionally a refresh token).
- API Access: The app uses the access token to make API requests on behalf of the user.
Benefits
- User Convenience: Users can log in with a familiar Google account instead of creating a new account.
- Security: Credentials are not shared with third-party applications.
- Granular Permissions: Users can control which resources an app can access.
- Token Revocation: Users can revoke permissions from their Google account dashboard.
Common Use Cases
- Social Login: Users can log into apps or websites using their Google account.
- API Integration: Access user-specific data from Google APIs (e.g., fetch calendar events or store files in Google Drive).
- Single Sign-On (SSO): Use Google OAuth2 for centralized authentication in corporate or personal systems.
