In theory one would have stored ones key only in #amber and every other app communicates with Amber to access it. But at the moment I've only seen Amethyst using a Amber feature that let's an App - even a web app - access Amber on Android. That feature is not even defined in NIP-46, whereas the communication setup using a QR code or ULR over a relay is not available at the moment. That would be useful for web apps in desktop browsers.
