+# Component: `auth0/app`
+
+Auth0 Application component. [Auth0](https://auth0.com/docs/) is a third-party service that provides authentication and
+authorization as a service. It is typically used to to authenticate users.
+
+An Auth0 application is a client that can request authentication and authorization from an Auth0 server. Auth0
+applications can be of different types, such as regular web applications, single-page applications, machine-to-machine
+applications, and others. Each application has a set of allowed origins, allowed callback URLs, and allowed web origins.
+
+## Usage
+
+Before deploying this component, you need to deploy the `auth0/tenant` component. This components with authenticate with
+the [Auth0 Terraform provider](https://registry.terraform.io/providers/auth0/auth0/latest/) using the Auth0 tenant's
+client ID and client secret configured with the `auth0/tenant` component.
+
+**Stack Level**: Global
+
+Here's an example snippet for how to use this component.
+
+```yaml
+# stacks/catalog/auth0/app.yaml
+components:
+  terraform:
+    auth0/app:
+      vars:
+        enabled: true
+        name: "auth0"
+
+        # We can centralize plat-sandbox, plat-dev, and plat-staging all use a "nonprod" Auth0 tenant, which is deployed in plat-staging.
+        auth0_tenant_stage_name: "plat-staging"
+
+        # Common client configuration
+        grant_types:
+          - "authorization_code"
+          - "refresh_token"
+          - "implicit"
+          - "client_credentials"
+
+        # Stage-specific client configuration
+        callbacks:
+          - "https://auth.acme-dev.com/login/auth0/callback"
+        allowed_origins:
+          - "https://*.acme-dev.com"
+        web_origins:
+          - "https://portal.acme-dev.com"
+          - "https://auth.acme-dev.com"
