Hi,
Not sure what information you are after - there is no way to securely persist login credentials in the simulator. There are several ways to store data insecurely but this is not acceptable to us and our users.
Malte and several other has replied to this in the past, most recently here: Navigraph in-game panel not bringing up log-in screen for charts - #19 by skysail
If your phone has stored you Navigraph account credentials you only need to scan and press Allow, no additional sign-in required. It breaks immersion, but literally only for a button press on your phone.
Regards,
Stephen
