How to Set Up Google Login Credentials (Google OAuth) for Your Website

Setting up Google Login for your website? This guide walks you through creating Google OAuth credentials step by step. From setting up a Google Cloud project to enabling APIs and configuring OAuth settings — everything you need is covered here!

Google OAuth credentials are essential for integrating secure user authentication into your application. Whether you’re building a web app, mobile app, or a service that requires access to Google APIs, this guide will walk you through creating OAuth credentials step-by-step.

Prerequisites

• A Google account.
• A Google Cloud project (created automatically upon setup).

Step 1: Access the Google Cloud Console

1. Navigate to Google Cloud Console.
2. Sign in or create an account if you don’t have one.
3. Select or create a project.

Step 2: Enable Required APIs

1. From the dashboard, click Explore and enable APIs under Getting started.
2. Search for APIs relevant to your application (e.g., Google Drive API, Gmail API, or Google Sign-In).
3. Enable the APIs you need.

Step 3: Navigate to the Credentials Section

In the left sidebar, go to APIs & Services > Credentials.

Here, you’ll see options to create API keys, OAuth clients, or service accounts.

Step 4: Set Up the OAuth Consent Screen

Before generating OAuth credentials, you must configure the OAuth consent screen:

1. Under APIs & Services, select OAuth consent screen.
2. Choose the user type (Internal for organization-only apps or External for public apps).
3. Fill in the required details:
   • App name: The name users see during OAuth consent (e.g., test).
   • User support email: A contact email for users.
   • Authorized domains: Add domains where your app will run (e.g., localhost for testing).
4. Save and proceed to the next steps.

Step 5: Generate OAuth Client ID Credentials

1. Return to Credentials > Create Credentials > OAuth client ID.
2. Select the Application type (e.g., Web application).
3. Provide a Name for your OAuth client (e.g., test).
4. Add Authorized redirect URIs
5. Click Create.

Step 6: Save Your Client ID and Secret

After creation, you’ll see a Client ID and Client Secret. Save these immediately:

1. Client ID: Public identifier for your app (e.g., 657611851911-a-v3...).
2. Client Secret: Confidential key for backend authentication (never expose this publicly).

Important Notes

1. Redirect URIs: Ensure URIs are correctly formatted and HTTPS-secured for production.
2. Security: Never share your client secret. Rotate it periodically via the Credentials page if compromised.

Next Steps

• Integrate the credentials into your app using Google’s OAuth 2.0 libraries.
• Test the authentication flow locally before deploying.
• Explore advanced settings like scopes and token management.

By following these steps, you’ve successfully generated Google OAuth credentials for secure user authentication in your application. For further details, refer to the Google OAuth Documentation.
