Enable Google Login on a White-Label Sparkforge Domain

By Sparkforge Support Team ·Last reviewed May 3, 2026

Agency admins can enable Sign in with Google on their Sparkforge white-label domain from Settings > Company > Whitelabel. Users then authenticate via Google OAuth.

Sparkforge supports Sign in with Google on white-label domains. Agency admins flip a toggle, users get a Google OAuth button on their login page.

Enable Google Login (agency admin)

  1. Log in to your agency account.
  2. Go to Settings > Company > Whitelabel.
  3. If your white-label domain is configured correctly, the Enable Google Login toggle appears. Turn it on.
  4. The white-label login page now shows a Sign in with Google button.

User login flow

  1. User visits the white-label domain and clicks Sign in with Google.
  2. The browser redirects to https://login.sparkforgehq.com/google?origin=<your whitelabel domain>.
  3. User must allow pop-ups for this URL — one-time per browser. Without it, the OAuth window will not appear.
  4. User selects the Google account registered with the agency.
  5. If the account is not associated with the agency, Sparkforge returns "User does not exist".
  6. On success, the user lands back on the login screen and is signed in.

Custom CSS

The new Google CTA does not break existing CSS. Agency admins may want to add styles for the button to match their brand — that is the only adjustment needed.

Frequently Asked Questions

Who can enable Google Login?
Agency Admins and Owners. The toggle lives at Settings > Company > Whitelabel and only appears when the white-label domain is correctly configured.
Why does the OAuth window not appear?
Pop-ups are blocked. Allow pop-ups for login.sparkforgehq.com once per browser. The Google OAuth screen will then load on subsequent attempts.
What does "User does not exist" mean?
The Google account selected is not registered with the white-label agency. Sign in with the Google account that matches the user's Sparkforge identity, or contact the agency admin to add the user.
Will Google Login break my custom CSS?
No. Existing styles still apply. You may want to add CSS for the new Sign in with Google button to match your brand, but nothing else needs to change.
