# User Logout

The `logout()` method can log an [app user](https://docs.catalyst.zoho.com/en/cloud-scale/help/authentication/user-management/users/introduction/) out from the Catalyst Android app.

The code syntax for user logout is given below:

```bash
ZCatalystApp.getInstance().logout(
    success: () → Unit,
    failure: (ZCatalystException) → Unit
    ): Unit

```

A sample code snippet is shown below:

```bash
ZCatalystApp.getInstance().logout(
    {
        ZCatalystLogger.logInfo("Logout Success")
            //Actions to execute on successful logout
    },
    { 
        ZCatalystLogger.logError("Logout failed - $it")
            //Actions to execute on failed logout
    })

```

The methods of the `ZCatalystLogger` class are used to log the result of the operation. You can define your own actions to execute upon a successful or failed logout.
