# ASWebAuthenticationSessionWebBrowserSessionManager

A session manager that mediates sharing data between an app and a web browser.

```
class ASWebAuthenticationSessionWebBrowserSessionManager
```

## Overview

You don’t create a session manager directly. Instead, use the [`shared`](/documentation/AuthenticationServices/ASWebAuthenticationSessionWebBrowserSessionManager/shared) session manager to tell the system what instance within your web browser app handles authentication requests. Do this by assigning an instance of a class that adopts the [`ASWebAuthenticationSessionWebBrowserSessionHandling`](/documentation/AuthenticationServices/ASWebAuthenticationSessionWebBrowserSessionHandling) protocol to the shared manager’s [`sessionHandler`](/documentation/AuthenticationServices/ASWebAuthenticationSessionWebBrowserSessionManager/sessionHandler) property.

You can also use the shared managers [`wasLaunchedByAuthenticationServices`](/documentation/AuthenticationServices/ASWebAuthenticationSessionWebBrowserSessionManager/wasLaunchedByAuthenticationServices) property to determine if your web browser app was launched for the specific purpose of performing authentication.
