I have a Windows Forms app using Auth0.OidcClient.WinForms to login to Auth0. Something seems to be getting cached and sometimes the login form doesn’t show.

**Desired**  
LoginAsync() opens the browser window so the user sees the login form every time.

**Actual**  
LoginAsync() sometimes does not open the browser window and the user is logged in automatically.  
This is a problem because we’re seeing this issue: if the user gives the wrong email and receives “access\_denied”, they will get this message forever. They never get a chance to see the login form again.

There’s nothing special about the code. Most of it came from the quickstart:

```auto
Auth0ClientOptions clientOptions = new Auth0ClientOptions
{
     Domain = _domain,
     ClientId = _clientId
};
_client = new Auth0Client(clientOptions);
clientOptions.PostLogoutRedirectUri = clientOptions.RedirectUri;

...

var extraParameters = new Dictionary<string, string>(); extraParameters.Add("organization", orgID);

...

LoginResult loginResult = await _client.LoginAsync(extraParameters: extraParameters);

```

How can I ensure the login form will pop up every time?

Hi @kendyl.drayer,

Welcome to the Auth0 Community!

You can use the `prompt="login"` parameter to force the login prompt. Alternatively, you can use the logout endpoint to terminate the session if you need to do so.
