[REQUIRED] Please describe the question here:

I want to disable auto-login, that is, I want to make that when the user opens my Desktop application current_user()->is_valid() evaluates to false (no currently active user).

At the moment the authentication state looks like to persist, I've tried avoiding this by signin-out as soon as I connect to the API:

m_firebase_app = firebase::App::Create(app_options);
m_firebase_auth = firebase::auth::Auth::GetAuth(m_firebase_app);
m_firebase_auth->SignOut();
m_firebase_auth->current_user().is_valid(); // Is still true with valid uid/email

But it does not work.

Another question: where is the authentication persisted on my local filesystem (which path)?
