## Example

### Access the `Session` object

The following example uses the [useSession()](https://clerk.com/docs/expo/reference/hooks/use-session.md) hook to access the [Session](https://clerk.com/docs/expo/reference/objects/session.md) object. The `Session` object is used to access the `lastActiveAt` property, which is a `Date` object used to show the time the session was last active.

filename: src/app/(session)/page.tsx
```tsx
import { useSession } from '@clerk/expo'
import { Text, View } from 'react-native'

export default function HomePage() {
  const { isLoaded, session, isSignedIn } = useSession()

  // Handle loading state
  if (!isLoaded)
    return (
      <View>
        <Text>Loading...</Text>
      </View>
    )

  // Protect the page from unauthenticated users
  if (!isSignedIn)
    return (
      <View>
        <Text>Sign in to view this page</Text>
      </View>
    )

  return (
    <View>
      <Text>This session has been active since {session.lastActiveAt.toLocaleString()}</Text>
    </View>
  )
}
```
