How this works
You add Supamodel as an app in your Google Admin console, then turn it on for the people who should have access. Usually that means a Google group, such as one called Supamodel users. When someone in that group signs in, Google checks who they are and sends them to Supamodel. The first time, Supamodel creates their account automatically. Anyone you haven’t turned the app on for is refused by Google. You can then give or remove access whenever you like, without contacting us. Not sure this is the right option? See Sign in with Google to compare it with option 1.Before you start
You need:- Super admin access to your company’s Google Workspace. If you don’t have it, ask your Google Workspace admin to follow this guide.
- The ACS URL and Entity ID we sent you. If you don’t have them, ask us.
- A Google group for the people who should have access, or an organisational unit. We recommend a group. You can create one now or in step 6.
Add Supamodel to Google Admin
1
Open the Google Admin console
Go to admin.google.com and sign in with your super admin account.
2
Create a custom SAML app
Go to Apps > Web and mobile apps. Click Add app > Add custom SAML app.
- App name:
Supamodel - Description and App icon: optional
3
Download the metadata
On the Google Identity Provider details page, click Download metadata. This saves a file called
GoogleIDPMetadata.xml. Keep it for later.Click Continue.4
Enter the Supamodel details
On the Service provider details page, enter:
- ACS URL: the ACS URL we sent you
- Entity ID: the Entity ID we sent you
- Start URL: leave empty
- Signed response: leave unticked
- Name ID format: EMAIL
- Name ID: Basic Information > Primary email
5
Map the user details
On the Attribute mapping page, click Add mapping three times and enter these values exactly:
Supamodel uses these to create each person’s account. Click Finish.
6
Choose who can use Supamodel
Open the Supamodel app, then click User access. New apps start switched OFF for everyone.To allow a group:
- In the left-hand panel, click Groups.
- Search for your group, for example Supamodel users, and select it.
- Set Service status to ON.
- Click Save.
Send us the metadata
Email theGoogleIDPMetadata.xml file to [email protected]. It doesn’t contain any secrets, so email is fine.
We connect it to your Supamodel account and let you know when it’s ready to test.
Test and switch over
1
Test with one person
We book a short call with you. Someone in your Supamodel group signs in with Google while we check everything works. Your current login keeps working throughout.You can also test the Google side yourself: open the Supamodel app in Google Admin and click Test SAML login.
2
Tell your team
Once the test passes, ask everyone in the group to reconnect. In Claude, they go to Customize > Connectors > Supamodel, click Disconnect, then Connect. Anyone who hasn’t added the connector yet can follow Connect Supamodel to Claude. On the sign-in page, they type their work email and continue with Google.
3
Agree a switch-off date
When everyone is using Google, we agree a date with you to switch off the old login.
Give or remove access later
To give someone access, add them to your Supamodel group in Google. They can sign in once Google applies the change. Their Supamodel account is created the first time they sign in. To remove someone’s access, remove them from the group, or suspend their Google account. Once Google applies the change, they can’t sign in again. They may stay connected for up to 12 hours, until their current session expires.Look after the Google app
The Supamodel app lives in your Google Admin console. Make sure at least one other admin at your company knows it exists and which group controls access. Google’s signing certificate for the app expires after 5 years. Google Admin shows the expiry date on the app’s page. Before it expires, create a new certificate in Google Admin and send us the new metadata file.Troubleshooting
Google says the person doesn't have access to this service

The app isn’t turned on for them yet. Check they’re in the right group, or wait for Google to apply the change. This can take up to 24 hours.
Google shows a 403 app_not_configured_for_user error

The Entity ID in Google Admin doesn’t match the one we sent you. Open the app, click Service provider details and check it.

Check the Attribute mapping in Google Admin. The app attribute names must match the table in step 5 exactly, including capital letters.
