Signing in to Luminous with Google
The Luminous sign-in portal supports Sign in with Google as a faster alternative to the one-time email link. When it is available, you will see a Google button on the sign-in page — no email inbox trip required.
Before you start
The Google sign-in button only appears when your Luminous account has Google SSO configured. If you don't see the button, your account is using email link sign-in — contact your Luminous administrator or Luminous Support if you believe Google SSO should be enabled for your team.
Signing in step-by-step
- Navigate to the Luminous sign-in page (
app.joinluminous.comor your custom URL). - If Google SSO is enabled, you will see a Sign in with Google button above the email field.
- Click Sign in with Google.
- A Google account chooser popup will appear. Select (or confirm) the Google account that matches your Luminous work email.
- Google confirms your identity and returns you to Luminous automatically.
- You will land on the workspace selector — choose the account you want to open.
Note: Your Google account email must match the work email address on your Luminous account. Signing in with a personal Gmail address that is not registered in Luminous will be declined.
The email link option is still available
If you prefer not to use Google, or if Google SSO is not enabled, you can still sign in by entering your work email and clicking Email me a sign-in link. Luminous will send a one-time link to your inbox — click it to complete sign-in.

|---|---|
| No "Sign in with Google" button | Google SSO is not configured for your account. Use the email link option, or ask your administrator. |
