# Stytch Login

> Implement the Stytch Login component using the Stytch React Native SDK

The React Native SDK provides the option for you to use pre-built login flows, supporting dark and light themes, with easy configuration, detailed below.

## Handling Deeplinks

For Email Magic Links, OAuth, SSO, and Password Reset flows, this component handles the deeplinking automatically. You'll need to add a custom URL scheme and redirect URL as explained below.

First, you need to configure your app to listen for a deeplink with the scheme: `stytch-ui-[YOUR_PUBLIC_TOKEN]`. How you do that will depend on your supported platforms and whether you are using [bare React Native](https://reactnative.dev/docs/linking) or [Expo](https://docs.expo.dev/guides/linking/#linking-to-your-app).

<Note>
  If you are using [Expo Router](https://docs.expo.dev/versions/latest/sdk/router/), which is the default for new apps created with create-expo-app, you must add a `+native-intent.tsx` file which ignores the incoming Stytch UI deep links. An example of this can be found [here](https://github.com/stytchauth/stytch-react-native-ui-expo-router/blob/main/app/%2Bnative-intent.tsx).
</Note>

Lastly, you'll need to add a special redirect URL in your Stytch Dashboard [Redirect URLs](https://stytch.com/dashboard/redirect-urls). It should have a URL of `stytch-ui-[YOUR_PUBLIC_TOKEN]://deeplink` and be applied to all redirect types.

Once both the scheme (in your app) and the redirect URL (in your Dashboard) are configured, our pre-built UI should handle the rest.

## Props

<ParamField path="client" type="StytchB2BClient" required>
  The Stytch B2B client object.
</ParamField>

<ParamField path="config" type="StytchRNB2BUIConfig" required>
  The config object for the UI components.

  <ParamField path="config.productConfig" type="StytchB2BUIConfig" required>
    The config object for the UI components.

    <Expandable title="properties">
      <ParamField path="products" type="B2BProducts[]" required>
        The products array allows you to specify the authentication methods that you would like to expose to your users.

        The order of the products that you include here will also be the order in which they appear in the login form, with the first product specified appearing at the top of the login form.

        Currently the SDK supports our `emailMagicLinks`, `oauth`, `sso`, and `passwords` products.

        `emailMagicLinks` and `oauth` are supported in both authentication flow types, whereas `sso` is only supported in the Organization authentication flow type. `passwords` is always supported in the Organization authentication flow type, but is also supported in the Discovery flow if cross-org passwords are enabled for the project.

        If the only product specified is `oauth`, and the only OAuth provider specified is google with `one_tap` set to true, the login form will not be displayed. Instead, we will only show the Google One Tap prompt in the upper right of the user's browser.
      </ParamField>

      <ParamField path="authFlowType" type="AuthFlowType" required>
        The authFlowType lets you specify the authentication flow type that you wish to enable in the SDK. The options are `Discovery` to let Members log into any Organization they are a part of; `Organization` to let Members log into a specific Organization; and `PasswordReset` to handle password reset flows (after the user clicks the password reset redirect URL). To enable the Organization flow type, you also must add a slug pattern to the authorized domain through the Frontend SDK page in the Dashboard.
      </ParamField>

      <ParamField path="sessionOptions" type="SessionOptions">
        The options for session management. We create a session for Members when they log in. You can access a Member or session using the Member or Session SDK methods.

            Set the session lifetime to be this many minutes from now; minimum of 5 and a maximum of 525600 minutes (365 days). Note that a successful authentication will continue to extend the session this many minutes.
          </ParamField>
        </Expandable>

          <ParamField path="loginTemplateId" type="string">
            Custom template ID for login emails. By default, it will use your default email template. Templates can be added in the [Stytch dashboard](https://stytch.com/dashboard/templates) using our built-in customization options or custom HTML templates with type “Magic links - Login”.
          </ParamField>

          <ParamField path="signupTemplateId" type="string">
            Custom template ID for sign-up emails. By default, it will use your default email template. Templates can be added in the [Stytch dashboard](https://stytch.com/dashboard/templates) using our built-in customization options or custom HTML templates with type “Magic links - Sign-up”.

          </ParamField>

          <ParamField path="resetPasswordTemplateId" type="string">
            Custom template ID for password reset emails, configured via [the Branding page](https://stytch.com/dashboard/templates) in the Stytch Dashboard. If this value is not specified, your default password reset template will be used.
