Tested with WordPress 5.8.1

by rtCamp.

Minimal plugin that allows WordPress users to log in using Google.

Ultra minimal plugin to let your users login to WordPress applications using their Google accounts. No more remembering hefty passwords!

Initial Setup

  1. Create a project from Google Developers Console if none exists.

  2. Go to Credentials tab, then create credential for OAuth client.

    • Application type will be Web Application
    • Add YOUR_DOMAIN/wp-login.php in Authorized redirect URIs
  3. This will give you Client ID and Secret key.

  4. Input these values either in WP Admin > Settings > WP Google Login, or in wp-config.php using the following code snippet:

    `
    define( ‘WP_GOOGLE_LOGIN_CLIENT_ID’, ‘YOUR_GOOGLE_CLIENT_ID’ );
    define( ‘WP_GOOGLE_LOGIN_SECRET’, ‘YOUR_SECRET_KEY’ );

Browser support

These browsers are supported. Note, for example, that One Tap Login is not supported in Safari.

How to enable automatic user registration

You can enable user registration either by
– Enabling Settings > WP Google Login > Enable Google Login Registration

OR

  • Adding
    define( 'WP_GOOGLE_LOGIN_USER_REGISTRATION', 'true' );
    in wp-config.php file.

Note: If the checkbox is ON then, it will register valid Google users even when WordPress default setting, under

Settings > General Settings > Membership > Anyone can register checkbox

is OFF.

Restrict user registration to one or more domain(s)

By default, when you enable user registration via constant WP_GOOGLE_LOGIN_USER_REGISTRATION or enable Settings > WP Google Login > Enable Google Login Registration, it will create a user for any Google login (including gmail.com users). If you are planning to use this plugin on a private, internal site, then you may like to restrict user registration to users under a single Google Suite organization. This configuration variable does that.

Add your domain name, without any schema prefix and www, as the value of WP_GOOGLE_LOGIN_WHITELIST_DOMAINS constant or in the settings Settings > WP Google Login > Whitelisted Domains. You can whitelist multiple domains. Please separate domains with commas. See the below example to know how to do it via constants:

`

define( ‘WP_GOOGLE_LOGIN_WHITELIST_DOMAINS’, ‘example.com,sample.com’ );
`

Note: If a user already exists, they will be allowed to login with Google regardless of whether their domain is whitelisted or not. Whitelisting will only prevent users from registering with email addresses from non-whitelisted domains.

Hooks

Filter wp_google_login_scopes
This filter can be used to filter existing scope used in Google Sign in.
You can ask for additional permission while user logs in.
This filter will provide 1 parameter scopes in callback, which contains array of scopes.

wp-config.php parameters list

  • WP_GOOGLE_LOGIN_CLIENT_ID (string): Google client ID of your application.

  • WP_GOOGLE_LOGIN_SECRET (string): Secret key of your application

  • WP_GOOGLE_LOGIN_USER_REGISTRATION (boolean) (optional): Set true If you want to enable new user registration. By default, user registration defers to Settings > General Settings > Membership if constant is not set.

  • WP_GOOGLE_LOGIN_WHITELIST_DOMAINS (string) (optional): Domain names, if you want to restrict login with your custom domain. By default, it will allow all domains. You can whitelist multiple domains.

BTW, We’re Hiring!

  1. Upload plugin-name.php to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Follow “Setup” instructions in ReadMe to configure credentials from Google Developers Console.
