Blocdash is a modular dashboard framework for WordPress block themes. Enable only the features you need and control access by role. It includes frontend login/register/profile forms, an announcements feed with likes and replies, and optional Google OAuth login.
<h3>External services</h3>
This plugin can connect to Google services when the optional Google Login and/or One Tap features are enabled.
Service: Google OAuth / Google Identity Services (One Tap) 
What it is used for: Allow users to authenticate with their Google account on the front-end login flow. 
What data is sent and when: 
– When a user initiates Google Login or One Tap, their browser loads Google’s Identity Services script and is directed to Google for authentication. 
– The site sends the OAuth authorization code, client ID, and client secret to Google’s token endpoint to obtain an access token. 
– The access token is then sent to Google’s userinfo endpoint to retrieve the user’s profile details (such as email address, name, and Google user ID) required to sign them in or create a WordPress account.
Terms of service: https://policies.google.com/terms 
Privacy policy: https://policies.google.com/privacy
<h3>Privacy</h3>
If Google Login or One Tap is enabled, the plugin sends requests to Google OAuth endpoints to authenticate users. No other external services are contacted by default.
