Google Single Sign-On (SSO) is an authentication process that allows users to log in to third-party applications or websites using their Google credentials. Here’s an explanation in table format:
| Concept | Explanation |
|---|---|
| Definition | A mechanism that allows users to authenticate into multiple services using a single Google account. |
| How It Works | |
| – User Login | The user selects the “Sign in with Google” option on the application/website. |
| – Redirection | The user is redirected to Google’s authentication server. |
| – Authentication | The user logs into their Google account (if not already authenticated). |
| – Authorization | Google prompts the user to grant permission to the application for accessing specific data. |
| – Token Exchange | Google issues an access token and ID token to the application. |
| – Access Granted | The application uses these tokens to authenticate and personalize the user session. |
| Components | |
| – OAuth 2.0 | Protocol used for secure authorization. |
| – OpenID Connect | Extension of OAuth 2.0 for identity verification. |
| – Access Tokens | Secure tokens issued to allow limited access to user data. |
| – ID Tokens | Tokens that verify user identity and contain user profile information. |
| Benefits | |
| – Convenience | Users don’t need to create and remember separate credentials for each application. |
| – Security | Google manages authentication, reducing risks like password theft for third-party applications. |
| – Integration | Simplifies the process for developers to integrate secure login functionality. |
| Use Cases | |
| – Web Applications | Logging into websites with a Google account. |
| – Mobile Apps | Streamlined sign-in for Android and iOS applications. |
| – Corporate Systems | Centralized login for enterprise applications leveraging Google Workspace. |
