Google Authentication

Add Google login to your application with a single prompt. Master Cloud handles the OAuth flow, redirect URL, and user storage.

Overview

Google sign-in is one of the fastest ways to allow users to log in without a password.

Enabling Google login

  1. Open Cloud → Users → Auth settings
  2. For the Google provider, click Enable
  3. (Optional) enter your own Google OAuth Client ID and Secret
  4. In the chat, type: "Add a Google sign-in button to the login page"
Without your own OAuth Client ID, shared Master OAuth will be used — it works instantly. For production, we recommend using your own Client ID.

Redirect URL and domains

If you use a custom domain, add it to the URI allow list in the auth settings. Set the Site URL to the URL of your published version.
