Ultra minimal plugin to let your users login to WordPress applications using their Google accounts. No more remembering hefty passwords!
<h3>Initial Setup</h3>
<ol>
<li>
Create a project from <a href="https://console.developers.google.com/apis/dashboard" rel="nofollow ugc">Google Developers Console</a> if none exists.
</li>
<li>
Go to Credentials tab, then create credential for OAuth client.
<ul>
<li>Application type will be Web Application</li>
<li>Add <code>YOUR_DOMAIN/wp-login.php</code> in Authorized redirect URIs</li>
</ul>
</li>
<li>
This will give you Client ID and Secret key.
</li>
<li>
Input these values either in <code>WP Admin > Settings > WP Google Login</code>, or in <code>wp-config.php</code> using the following code snippet:
<code>define( 'WP_GOOGLE_LOGIN_CLIENT_ID', 'YOUR_GOOGLE_CLIENT_ID' ); 
define( 'WP_GOOGLE_LOGIN_SECRET', 'YOUR_SECRET_KEY' );</code>
</li>
</ol>
<h3>Browser support</h3>
<a href="https://developers.google.com/identity/gsi/web/guides/supported-browsers" rel="nofollow ugc">These browsers are supported</a>. Note, for example, that One Tap Login is not supported in Safari.
<h3>How to enable automatic user registration</h3>
You can enable user registration either by 
– Enabling Settings > WP Google Login > Enable Google Login Registration
OR
<ul>
<li>Adding 
<code>define( 'WP_GOOGLE_LOGIN_USER_REGISTRATION', 'true' );</code> 
in wp-config.php file.</li>
</ul>
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.
<h3>Restrict user registration to one or more domain(s)</h3>
By default, when you enable user registration via constant <code>WP_GOOGLE_LOGIN_USER_REGISTRATION</code> 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 <code>www,</code> as the value of <code>WP_GOOGLE_LOGIN_WHITELIST_DOMAINS</code> constant or in the settings <code>Settings > WP Google Login > Whitelisted Domains</code>. You can whitelist multiple domains. Please separate domains with commas. See the below example to know how to do it via constants: 
 <code>define( 'WP_GOOGLE_LOGIN_WHITELIST_DOMAINS', 'example.com,sample.com' );</code>
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.
<h3>Hooks</h3>
For a list of all hooks please refer to <a href="https://github.com/rtCamp/login-with-google#hooks" rel="nofollow ugc">this documentation</a>.
<h4>wp-config.php parameters list</h4>
<ul>
<li>
<code>WP_GOOGLE_LOGIN_CLIENT_ID</code> (string): Google client ID of your application.
</li>
<li>
<code>WP_GOOGLE_LOGIN_SECRET</code> (string): Secret key of your application
</li>
<li>
<code>WP_GOOGLE_LOGIN_USER_REGISTRATION</code> (boolean) (optional): Set <code>true</code> If you want to enable new user registration. By default, user registration defers to <code>Settings > General Settings > Membership</code> if constant is not set.
</li>
<li>
<code>WP_GOOGLE_LOGIN_WHITELIST_DOMAINS</code> (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.
</li>
</ul>

TeddyID Lite allows your users to log in without entering a password, yet more securely.
Users will have to enter a password only once, TeddyID will suggest encrypting and saving the password. The next time the user tries to log in, the user just clicks his username (see the screenshot), we pick a random picture and send it to user’s two devices: his computer and his phone (with our free app installed). The user makes sure the pictures match and taps “Yes” on his phone. We decrypt the password, fill it in, and submit the form. Login complete.
With TeddyID Lite, your users won’t have to remember, nor type, the password for your site. This is a free service for WordPress based sites.
Nothing is changed in your wordpress database. Passwords are encrypted/decrypted only in browser.

Teddy ID Lite

Enables your users to log in to your site without manually entering the password. Instead, user just taps one button on his phone.
