Simple Easy Social Login – OAuth Login

Simple Easy Social Login is a lightweight WordPress plugin that allows you to add fast and easy social login functionality to your website.

It supports Google, Facebook, and LinkedIn (Free), as well as Naver, Kakao, and Line (Premium), and is designed to work especially well for websites targeting users in Asia (Korea, Japan, China) as well as Europe and South America.

The plugin integrates seamlessly with the WordPress login and registration pages, and also works smoothly with WooCommerce login and registration forms.
User social profile images (avatars) can be automatically synchronized with WordPress user profiles.

This plugin creates new WordPress user accounts only when a user logs in with a social provider and no matching account exists.
User creation strictly respects both the WordPress core setting “Anyone can register” and the plugin’s own “Automatic User Creation” option (enabled by default).

We fire the standard WordPress wp_login action after setting the auth cookie so that security plugins (such as brute-force protection, 2FA, and login logging tools) can hook into the normal login flow without being bypassed.

Administrators can disable automatic user creation in the plugin settings if they prefer only existing users to log in via social providers.

The plugin is built on an extensible Provider-based architecture, which allows new OAuth Providers to be added later as separate Add-on plugins if needed.

External services

This plugin connects to third-party OAuth providers to enable social login functionality. These services are only contacted when a user initiates a login action by clicking a social login button.

For each provider, the plugin sends an OAuth authorization request and exchanges an authorization code for an access token. Basic profile data may be retrieved depending on the configured scopes.
