# useRefreshUser

<Warning>
  Available from SDK V3.0+
</Warning>

## Summary

Used to manually refresh the user state at any point in time, for example if you have multiple separate windows (things like a Chrome extension popup and a Chrome page for the same extension) where Dynamic is active and you want to ensure they are all in sync.

The SDK state as a whole will be maintained i.e. the `sdkHasLoaded` boolean on `useDynamicContext` will stay true. If you want to reset the whole SDK including wallets, then take a look at [`useReinitialize`](/react-sdk/hooks/usereinitialize).

## Usage

```tsx
import {
  DynamicContextProvider,
  useRefreshUser,
} from '@dynamic-labs/sdk-react-core';

const RefreshButton = () => {
  const refresh = useRefreshUser();

  return (
    <button onClick={refresh}>Reinitialize</button>
  );
}

const App = () => {
  return (
    <DynamicContextProvider>
      <RefreshButton />
    </DynamicContextProvider>
  )
}
```
