Auth

WorkOS

Use WorkOS with your Supabase project

WorkOS can be used as a third-party authentication provider alongside Supabase Auth, or standalone, with your Supabase project.

Getting started

  1. First you need to add an integration to connect your Supabase project with your WorkOS tenant. You will need your WorkOS issuer. The issuer is https://api.workos.com/user_management/<your-client-id>. Substitute your custom auth domain for "api.workos.com" if configured.
  2. Add a new Third-party Auth integration in your project's Authentication settings.
  3. Set up a JWT template to assign the role: 'authenticated' claim to your access token.

Add a new Third-Party Auth integration to your project

In the dashboard navigate to your project's Authentication settings and find the Third-Party Auth section to add a new integration.

Set up a JWT template to add the authenticated role.

Your Supabase project inspects the role claim present in all JWTs sent to it, to assign the correct Postgres role when using the Data API, Storage or Realtime authorization.

WorkOS JWTs already contain a role claim that corresponds to the user's role in their organization. It is necessary to adjust the role claim to be "authenticated" like Supabase expects. This can be done using JWT templates (navigate to Authentication -> Sessions -> JWT Template in the WorkOS Dashboard).

This template overrides the role claim to meet Supabase's expectations, and adds the WorkOS role in a new user_role claim:
