# invalidate()

Inmediately invalidates a session.

## Declaration

```swift
func invalidate() async throws
```

## Discussion

Discussion Call this method when your app no longer needs a credential session. The system automatically invalidates a session when it deallocates, or when it encounters underlying errors. When a session invalidates, its event stream also invalidates and deallocates. You can invalidate a session while in any session state.
