 `AUTH_NO_ORIGIN` will appear as a warning message during development and be thrown as an error that stops the application during production.
 It is safe to ignore the development warning - it is only meant as a heads-up for your later production-deployment.
 
-`AUTH_NO_ORIGIN` occurs when the origin of your application was not set.
-NuxtAuth attempts to find the origin of your application in the following order ([source](https://github.com/sidebase/nuxt-auth/blob/9852116a7d3f3be56f6fdc1cba8bdff747c4cbb8/src/runtime/server/services/utils.ts#L8-L34)):
+`AUTH_NO_ORIGIN` occurs when the authentication base URL of your application was not set.
 
-### 1. Environment variable and `runtimeConfig`
+For a detailed guide on pathing logic, refer to its [dedicated page](../guide/advanced/url-resolutions.md).
 
-Use the `AUTH_ORIGIN` environment variable or `runtimeConfig.authOrigin` if set. Name can be customized, refer to [`originEnvKey`](/guide/application-side/configuration#originenvkey).
+The simplest way to fix this error is by providing `auth.baseUrl` in your `nuxt.config.ts`:
 
-### 2. `baseURL`
-
-The `origin` is computed using `ufo` from the provided `baseURL`. See implementation [here](https://github.com/sidebase/nuxt-auth/blob/9852116a7d3f3be56f6fdc1cba8bdff747c4cbb8/src/runtime/helpers.ts#L9-L23).
-
-```ts
+```ts [nuxt.config.ts]
 export default defineNuxtConfig({
   auth: {
-    baseURL: `http://localhost:${process.env.PORT || 3000}`
-  }
+    baseUrl: 'https://example.com/api/auth', // [!code ++]
+  },
+  // ... other configuration
 })
 ```
 
-### 3. Development only: automatically from the incoming HTTP request
-
-When the server is running in development mode, NuxtAuth can automatically infer it from the incoming request.
-
-::: info
-This is only done for your convenience - make sure to set a proper origin in production.
-:::
-
----
-
-If there is no valid `origin` after the steps above, `AUTH_NO_ORIGIN` error is thrown in production.
+For setting your authentication base URL dynamically, refer to [Changing `baseURL`](../guide/advanced/url-resolutions.md#changing-baseurl).
