WebAuthenticator relogin without showing loging dialog from OAuth Provider

[haeberle]

Description

I'm following this guide to implement the web authentication in a .net Maui application and it works well.

The user calls the WebAuthenticator for login, as shown in the example above, and successfully logs in. After some time, the user needs to log in again to the OAuth server to renew the access token in order to access backend services.

For this purpose, the WebAuthenticator is called again.

Expected Behavior: The WebAuthenticator opens the login dialog of the OAuth provider, and upon successful login, the backend server sends the tokens.

Actual Behavior: The WebAuthenticator performs the login directly without displaying the OAuth provider’s login dialog.

Assumption: The WebAuthenticator caches the login data, and the OAuth provider dialog is called with this cached information.

Solution: This behavior is not inherently bad for all use cases, but there should be an option to clear the WebAuthenticator’s cache.
