Customizing the Google login

Base44 gives you 2 ways to set up Google login, so you can manage how your users experience sign-in and how your brand is displayed:
  • Default Google login: Fast setup using Base44’s credentials. The login window shows “Sign in with Google” and is branded with base44.com. To use this method, enable the Google authentication toggle and select Use the default Base44 OAuth.

  • Custom Google OAuth: Connect your own Google Cloud client ID and secret in the Authentication panel. Your users will see your app’s domain, not “base44.com” when they sign in with Google. Custom Google OAuth is a great choice if you want full control over your login branding or need your app’s domain and messaging to appear in the Google login window. This is ideal for businesses that require a fully branded experience or need to meet enterprise requirements.
Custom Google OAuth login screen
Before you begin:
To set up custom Google OAuth:
  1. Connect a custom domain to your app.
  2. Go to Google Cloud Console and create a new project for your app.
  3. Verify your domain here.
  4. Set up your OAuth app by completing the following information: Setting up your OAuth app
    1. Overview: Enter your app information.
    2. Branding: Set up your app’s branding (learn more about branding):
      1. Add your logo. This must be similar to your app’s logo.
      2. Create a home page in your app following these guidelines.
      3. Create a privacy policy linked from your home page following these guidelines. 
      4. Add a support page to your app.
      5. Add your domain as an authorized domain.
    3. Audience: Choose if your app is for internal or external use.
    4. Clients: Get your Client ID and Secret:
      1. Click Create client.
      2. Enter the relevant details including the following:
      • Authorized JavaScript origins: Enter your app domain.

      You must add a landing page to your app that includes your privacy policy and terms of service. These pages must be public and not behind a login. This is required for Google OAuth approval and lets your users see your legal information before signing in.
  5. Go back to Base44 and finish setting up your custom login:
    1. Click Dashboard in your app editor.
    2. Click Settings.

Collecting data at sign-up

Personalize your app experience by collecting key details from your users when they sign up. You can prompt the chat to generate a custom sign-up form that gathers information beyond just an email and password (e.g. full name, company, or role) so you can onboard people smoothly and tailor their app experience from the start. Choose where to store the data:
  • Users dataset: Store data securely, viewable only by app admins. This is ideal for sensitive or admin-only details.
  • Connected dataset: Store user responses in a separate public-facing dataset. This is recommended for data displayed or shared in-app (like company names).

FAQs

Click a question below to learn more about authentication.
If users don’t receive verification or password reset emails, try these fixes:
  • Check spam folders to see if the email was marked as spam.
  • Whitelist app@base44.com to make sure their email provider doesn’t mark it as spam.
  • Avoid capitalizing letters in the email address during sign-up.
If it still doesn’t work, remove the user from Users and have them sign up again.
It’s not possible to make some pages in your app public and keep others private. We know this is a common request, and we’re actively working on adding it. You can follow progress (and add your voice) here: Hybrid Apps – Authentication Support .As a workaround, to set up your Base44 app so that everyone can visit your landing page while requiring users to log in for other pages, follow these steps:
  1. Set your app to Public (no login required):
    In your Dashboard, go to Settings → App Settings. Set App Visibility to Public (no login required). This allows anyone to see your landing page.
  2. Create your landing page with login and sign-up buttons:
    Prompt the AI to “create a landing page with login and sign-up buttons.” Make sure this is your app’s main page by selecting it under “Main Page” in your settings.
  3. Require login for other pages:
    Ask the AI to require login on all other pages and redirect visitors who aren’t logged in back to your landing page.
With this setup, all visitors see your landing page first. Only users who have logged in or signed up can view the rest of your app’s pages.
Base44 automatically handles all passwords securely behind the scenes. If someone forgets their password, they can reset it directly from the login screen by clicking Forgot password?.Use login sceen with Forgot password option to reset it.

No, Base44 does not currently support creating a fully custom authentication flow from scratch. This means you cannot build your own authentication pages, change the design or language of the built-in auth screens, or fully white label the authentication process. Authentication is managed by the platform to keep your app secure and consistent.Features like white labeling are planned for the future, but are not available yet. Check out the feature request for more information.
You can use SSO with platforms such as Google, Microsoft, GitHub, or Okta. For step-by-step instructions, see the guide on setting up SSO in Base44.If your identity provider supports OIDC (OpenID Connect) and you are on the Elite plan, you can try the “Advanced / Manual configuration” option:Advancedconfiguration Pn
