To integrate Google and Facebook authentication for user registration and login in WordPress, you can use third-party plugins that simplify the process. Here’s a step-by-step guide on how to do this:
Install Required Plugins:
Navigate to Plugin > Add New plugin and search “Nextend Social Login” install and activate this plugin.


Navigate to Settings > Nextend Social Login option click and Connect your WordPress site to Google and Facebook.


Create API Keys:
Google API Keys:

- Name your project and then click on the “Create” button again!

- Once you have a project, you’ll end up in the dashboard. ( If earlier you have already had a Project, then make sure you select the created project in the top bar! )

- Click the “OAuth consent screen” button on the left hand side.

- Choose a User Type according to your needs and press “Create”. If you want to enable the social login with Google for any users with a Google account, then pick the “External” option!

- Enter a name for your App to the “App name” field, which will appear as the name of the app asking for consent.

- For the “User support email” field, select an email address that users can use to contact you with questions about their consent.

- Under the “Authorized domains” section press the “Add Domain” button and enter your domain name, probably: demo7.wpengineers.com without subdomains!

- At the “Developer contact information” section, enter an email address that Google can use to notify you about any changes to your project.

- Press “Save and Continue” then press it again on the “Scopes”, “Test users” pages, too!

- A modal should pop up with your credentials. If that doesn’t happen, go to the Credentials in the left hand menu and select your app by clicking on its name and you’ll be able to copy-paste the “Client ID” and “Client Secret” from there.

- Currently your App is in Testing mode, so only a limited number of people can use it. To allow this App for any user with a Google Account, click on the “OAuth consent screen” option on the left side, then click the “PUBLISH APP” button under the “Publishing status” section, and press the “Confirm” button.

- Press the “Save changes” button.

- By default, your application only has Standard Access for the “public_profile” and “email” permissions, which means that only you can log in with it. To get Advanced Access you will need to go through the Business Verification, that you can start on the “Verification” tab on the left side.


- Currently your app is in Development Mode which also means that people outside of your business can not use it. Once your verification is completed, click on the “Go live” tab and publish your app by clicking on the “Go live” button at the bottom right corner. Before you press it, it is recommended to check the steps listed on the “Go live” page, if you configured everything properly.

- After everything is done, click on the “Settings” tab, then click “Basic”.
- At the top of the page you can find your “App ID” and you can see your “App secret” if you click on the Show button. These will be needed in the plugin’s settings.
