Login with Facebook

Facebook sign-in needs an app in the Meta developer console with the Facebook Login product added. Meta’s console changes layout often; the names below are current as of 2026, and the steps are the same even when the buttons move.

1. Create the app

1. Open developers.facebook.com and sign in.
2. My Apps → Create App. Use case: Other. App type: Consumer. Give it a name and a contact email.

2. Basic settings

Under App settings → Basic:

• App domains: your domain without the protocol, e.g. example.com.
• Privacy policy URL: required before the app can go live. Your site’s privacy page.
• User data deletion: a URL describing how users can ask for their data to be removed. Your privacy page is acceptable if it explains this.
• App icon (1024 × 1024) is optional but shows on the consent dialog.

Save changes.

3. Add Facebook Login

1. In the left sidebar, Add product → Facebook Login → Set up.
2. Under Facebook Login → Settings:

   • Valid OAuth redirect URIs: your login page,

     https://example.com/wp-login.php

   • Client OAuth login: yes.

   • Web OAuth login: yes.

3. Save.

4. Permissions

Under App review → Permissions and features, request Advanced access for email and public_profile. These two are granted automatically for consumer apps once your app has a privacy policy; no manual review is needed.

5. Go live

Switch the app from Development to Live using the toggle at the top of the console. In development mode only the app’s own developers and testers can sign in.

6. Connect it to FluentAuth

Under App settings → Basic, copy the App ID and App secret (click Show). Paste them on the Facebook card under FluentAuth → Settings → Social Login, or add them to wp-config.php:

define('FLUENT_AUTH_FACEBOOK_CLIENT_ID', '…');
define('FLUENT_AUTH_FACEBOOK_CLIENT_SECRET', '…');

Turn on Enable login with Facebook and save.
