# Logout user

To sign out the user, use the `logout` method. It invalidates the current session, clears the session data that the SDK stored in the Keychain, and sets `web3Auth.web3AuthResponse` to `nil`. The user must sign in again to use the dapp the next time the dapp is opened.

warning

`logout` deletes every generic password item in your app's Keychain, not only the items the SDK created. This includes your app's own generic password items and any stored dapp shares. Store data you need to keep after sign-out in another Keychain item class or another storage location.

## Usage

```swift
try await web3Auth.logout()

```
