# useGetMfaToken

> [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

This hook provides a way for clients to get an MFA token for an action which requires MFA.

The hook needs to be initialized within a child of [DynamicContextProvider](https://docs.dynamic.xyz/docs/react/reference/providers/dynamiccontextprovider.md).

### Usage

Available methods:

* `getMfaToken`: Get an MFA token for an action which requires MFA.

### Usage

```TypeScript theme={"system"}
import { useGetMfaToken } from '@dynamic-labs/sdk-react-core';

const App = () => {
  const getMfaToken = useGetMfaToken();

  return (
    <button
      onClick={() => getMfaToken()}
    >
      Get MFA token
    </button>
  );
};
```
