Adding a Google login system to your WordPress site can significantly improve the user experience. It allows visitors to register and sign in easily, using their Google credentials. In this article, we're going to explore the full process of implementing this functionality, from creating a Google Cloud project to integrating it into your WordPress website.
Creating a Google Cloud Project
Before you can integrate Google sign-in, you need to create a Google Cloud project. This step is essential to obtain the necessary credentials that will allow you to authenticate users.
Steps to create a project
- Access to Google Cloud Console at console.cloud.google.com.
- Sign in with your Google account.
- Click on the project drop-down menu at the top and select New Project.
- Assign a name to your project and click on Create.
Once the project is created, you will need to enable the Google sign-in API, which is crucial for authentication to work properly.
Enabling the Google Sign-in API
- In the navigation pane, search for APIs and services and select Library.
- Search Google+ API o Google Identity Services and click on Enable.
With this, your project will be ready for the next phase: the configuration of the credentials.

- Click on Create credentials and choose OAuth Client ID.
- Select the type of application as Web application.
- Set up consent screens and add redirection URIs (you can use http://tudominio.com/wp-admin/ for testing).
