# onAuthSuccess

<Card title="Recommended: JavaScript SDK with React Hooks" icon="react" color="#4779FE">
  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)](/javascript/reference/react-quickstart) to get started.
</Card>

### Summary

This callback will be called after the user successfully authenticates.

### Usage

```TypeScript theme={"system"}
<DynamicContextProvider
  settings={{
    events: {
      onAuthSuccess: (args) => {
        console.log('onAuthSuccess was called', args);
        // you can get the jwt by calling the getAuthToken helper function
        const authToken = getAuthToken();
        console.log('authToken', authToken);
      }
    }
  }}
