+### Provider: `refresh`
+
+The refresh provider does not require any additional steps, as it relies on an already existing backend. By default, the `refresh` provider will try to reach this backend using the following default-configuration:
+```ts
+{
+    baseURL: '/api/auth',
+    endpoints: {
+        signIn: { path: '/login', method: 'post' },
+        signOut: { path: '/logout', method: 'post' },
+        signUp: { path: '/register', method: 'post' },
+        getSession: { path: '/session', method: 'get' }
+        refresh: { path: '/refresh', method: 'post' },
+    }
+}
+```
+
+So when you call the `signIn` method, the endpoint `/api/auth/login` will be hit with the `username` and `password` you pass as a body-payload. You likely have to modify these parameters to fit to your backend - you can adjust these parameters in your `nuxt.config.ts` using the options [specified here](/nuxt-auth/v0.6/configuration/nuxt-config).
+
+Note: The backend can also be in the same Nuxt 3 application, e.g., have a look at this example in the `nuxt-auth` repository:
+- [full nuxt app](https://github.com/sidebase/nuxt-auth/tree/main/playground-refresh)
+    - its [backend](https://github.com/sidebase/nuxt-auth/tree/main/playground-refresh/server/api/auth)
+    - its [`nuxt.config.ts`](https://github.com/sidebase/nuxt-auth/blob/main/playground-refresh/nuxt.config.ts)
+
+::alert{type="info"}
+The linked example-implementation only serves as a starting-point and is not considered to be secure.
+::
+
+The backend must accept a request with a body like:
+```ts
+{
+    username: '[email protected]',
+    password: 'hunter2'
+}
+```
+
+and return a token that can be used to authenticate future requests in the response body, e.g., like:
+```ts
+{
+    tokens: {
+        accessToken: 'eyBlaBlub'
+        refreshToken: 'eyBlaubwww'
+    }
+}
+```
+
+So when you call the `refresh` method, the endpoint `/api/auth/refresh` will be hit with the `refreshToken` you pass as a body-payload. You likely have to modify these parameters to fit to your backend - you can adjust these parameters in your `nuxt.config.ts` using the options [specified here](/nuxt-auth/v0.6/configuration/nuxt-config).
+
 ## Finishing up
 
 That's it! You can now use all user-related functionality, for example:
 
 ::code-group
 ```ts [Application side]
 // file: e.g ~/pages/login.vue
-const { status, data, signIn, signOut } = useAuth()
+const { status, data, signIn, signOut, refresh   } = useAuth()
 
 status.value // Session status: `unauthenticated`, `loading`, `authenticated`
 data.value // Session data, e.g., expiration, user.email, ...
 
 await signIn() // Sign in the user
+await refresh() // Refresh the token 
 await signOut() // Sign out the user
+
 ```
 ```ts [authjs: Server side]
 // file: e.g: ~/server/api/session.get.ts
