First login to your Google Cloud Account and use an existing project or create a new one.
After that, go to Credentials menu and press the button CREATE CREDENTIALS, select the option OAuth Client ID.
Select your application type and set a description name
If successful, you will get your Client Id and Client Secret
Don't share your OAuth2 data with anyone!
