# handleAuthenticatedUser

> [card] Recommended: JavaScript SDK with React Hooks
>
> For new React apps, we recommend the JavaScript SDK with React Hooks (`@dynamic-labs-sdk/react-hooks`) instead of the legacy React SDK documented here. The JS SDK comes with many benefits such as a much smaller bundle size and other optimizations. Use the [React quickstart (JavaScript SDK)](https://docs.dynamic.xyz/docs/javascript/reference/react-quickstart.md) to get started.

### Summary

A handler runs after the user is authenticated and allows for a custom code to handle the user object before the Dynamic SDK finishes the authentication and closes the UI.

### Usage

```jsx theme={"system"}
<DynamicContextProvider
  settings={{
    handlers: {
      handleAuthenticatedUser: async (args) => {
        console.log("handleAuthenticatedUser was called", args);

        await customUserObjectProcess(args.user);
      },
    },
  }}
>
  {/* ... rest of your app ... */}
</DynamicContextProvider>
```

### Handler Argument Value

[UserProfile](https://docs.dynamic.xyz/docs/react/reference/objects/userprofile.md) Authenticated user
