The terminology is a bit confusing. I mean mobile apps acting as signers. A nostr website could show a QR code for logging in with your mobile app, you scan it with Amethyst/Damus/Primal and you are logged in. No need to install another app like Amber but have this functionality on mobile clients. Maybe I'm misunderstanding something but `nostrconnect` URLs enable this flow, no?

Terminology is confusing, your ask is nip46 server in Damus/Amethyst/Primal, nostrconnect as QR scanned by the mobile app-signer should work, I think.
+1, would be great UX imo. I haven't seen support for nostrconnect URL QRs in clients that support NIP-46 login tho.
