Obtain the Google Client ID and Secret for authentication

Development, Authentication, Google, Security

To obtain the Google Client ID and Secret for authentication, you need to create a new Google OAuth 2.0 Client ID in the Google Developers Console. Here’s a step-by-step guide:

  1. Go to the Google Developers Console: https://console.developers.google.com/
  2. If you haven’t already, sign in with your Google account and agree to the terms of service.
  3. Click on the project dropdown in the top navigation bar and select or create a new project for your application.
  4. In the left sidebar, click on “APIs & Services” and then click on “Credentials”.
  5. Click on the “CREATE CREDENTIALS” button at the top and select “OAuth client ID” from the dropdown menu.
  6. If you haven’t configured the OAuth consent screen before, you will be prompted to do so. Click on “CONFIGURE CONSENT SCREEN” and fill in the required information about your application, such as the application name, support email, and developer contact information. Save the consent screen settings.
  7. In the “Application type” section, select “Web application” for a web-based application or “Desktop app” for a desktop application.
  8. Provide a name for your OAuth 2.0 client, such as “My App OAuth Client”.
  9. In the “Authorized JavaScript origins” field, enter the URLs of your application’s pages that will use the OAuth 2.0 client. For local development, you can enter http://localhost or http://localhost:port, where port is the port number your application runs on.
  10. In the “Authorized redirect URIs” field, enter the callback URL(s) where Google will redirect the user after authentication. This URL should match the one you will use in your application to handle the OAuth callback.
  11. Click on the “CREATE” button to create the OAuth 2.0 Client ID.
  12. After creation, you will see the “Client ID” and “Client Secret” values. Make note of these values as you will need them in your application’s configuration to enable Google authentication.
  13. Configure your application to use the obtained Client ID and Client Secret for Google authentication. The exact steps may vary depending on the programming language and framework you are using. Typically, you will need to provide these values in your application’s configuration file or environment variables.

Remember to keep the Client Secret confidential and do not expose it publicly in your application’s source code or client-side code.

With the Google Client ID and Secret, you can now integrate Google authentication into your application using the Google OAuth 2.0 flow. The authentication process typically involves redirecting the user to the Google login page, obtaining an authorization code, exchanging the code for an access token, and retrieving the user’s information using the access token.

The specific implementation details will depend on the programming language, framework, and libraries you are using for your application.
