To create a Google OAuth client ID and client secret, you need to follow the steps below:

Go to the Google Cloud Console: Visit the Google Cloud Console at https://console.cloud.google.com/ and sign in with your Google account.

Create a new project: If you don't have a project yet, create a new project by clicking on the project drop-down menu at the top of the page and selecting "New Project". Give your project a name and click "Create".

Enable the necessary APIs: In the Cloud Console, go to the "APIs & Services" section. Click on "Library" in the left-hand menu. Search for and enable the following APIs:

Google OAuth 2.0 API Google+ API (if needed) Set up OAuth consent screen: In the Cloud Console, navigate to the "APIs & Services" section and click on "OAuth consent screen" in the left-hand menu. Choose an appropriate user type and fill in the required information, such as the application name and authorized domains.

Create OAuth client ID: In the Cloud Console, go to the "APIs & Services" section and click on "Credentials" in the left-hand menu. Click on the "Create Credentials" button and select "OAuth client ID" from the drop-down menu.

Configure the OAuth client ID: Choose the application type, such as "Web application" or "Android/iOS app". Enter the necessary details, including authorized JavaScript origins or redirect URIs, depending on your application type. Save the configuration.

Obtain the client ID and client secret: Once you've created the OAuth client ID, the client ID and client secret will be displayed on the "Credentials" page. Make sure to copy and securely store these values as they are required for authenticating your application

then store these values in .env file CLIENT_ID = "" // OAuth client ID CLIENT_SECRET = "" // OAuth client secret CALLBACK_URL = "" // callback URL like (http://localhost:5000/auth/google/callback) in place of localhost put the live server's link where you will receive callback successURL = "" // this URL will redirect user to the page where we want send him after succesfull authentication for example Home page URL(https://mern-notebook.onrender.com/)
