# \<LoginForm>

## Overview

Use `<LoginForm />` instead of [\<Form />](/develop/react/api-guide/form.md) to display your login & signup flow. It provides critical authentication-related logic, including:

* For logged out users, show the login or signup step of your flow. Prevent users from accessing your authenticated app until they log in.
* Once a user logs in, display either the [first-time onboarding flow](broken://pages/sv8DAAQsHViLKqJnB3UL) (if included in your login form) or the authenticated part of your custom app.
* (Optional) Automatically log the user out of the application after their session expires after a period of inactivity.

### Example Code

{% code lineNumbers="true" %}

```jsx
<LoginForm
  formProps={{
    formId: 'aBcDeF',
    onSubmit,
    onSkip
  }}
  loginPath='/'
  onLogin={fetchBackendResources}
  onLogout={() => (window.location.href = window.location.origin)}
  >
    <Router>
      <Switch key={window.location.href}>
        <Route exact path='/'>
          <RootPage />
        </Route>
        <Route exact path='/your/path'>
          <YourComponent />
        </Route>
      </Switch>
    </Router>
</LoginForm>
```

{% endcode %}

Setting this denotes the user as <code>logged in</code> and will track their authenticated account information.</td></tr><tr><td><code>authClient</code></td><td><code>optional instance of auth SDK</code></td><td>If you don't specify this, Feathery will dynamically install the JS SDK itself that you can use with <a href="/pages/OVsZJMZk0iaDSyiOjEK9">getAuthClient()</a>. If you want to initialize this yourself and pass it to Feathery, you can do so with this prop.</td></tr><tr><td><code>loader</code></td><td><code>optional JSX component</code></td><td>A custom loader to show while waiting for auth network calls and, if applicable, your <code>onLogin</code> call. If not provided, a default spinner will be used.</td></tr><tr><td><code>loginPath</code></td><td><code>optional string</code></td><td>OAuth 2.1 requires login paths to be whitelisted, so this prop allows you to specify a path you've whitelisted in your auth provider that the user should be directed to when showing the login flow. Defaults to <code>/</code></td></tr><tr><td><code>onClientReady</code></td><td><code>optional function</code></td><td>A callback function that runs after the auth SDK has been initialized. The function passes the SDK client as the single parameter.</td></tr><tr><td><code>onLogin</code></td><td><code>optional async function</code></td><td>A callback function that runs after the user has been successfully authenticated. This function will run to completion before the provider <code>children</code> are rendered, so you can load anything your application needs here.</td></tr><tr><td><code>onLogout</code></td><td><code>optional function</code></td><td>A callback function that runs after the user has logged out. </td></tr><tr><td><code>children</code></td><td><code>optional JSX components</code></td><td>Pass the authenticated portion of your app as <code>children</code> of the <code>LoginProvider</code> component. You can also pass no <code>children</code> if you just want to render the login flow with no protected resource.</td></tr></tbody></table>
