I am curious about PassKey … not as a replacement for passwords (Nostr keys already do this) but as a “third party key generator, signer, and manager” for Nostr clients. (Like Amber currently does, but using an industry standard protocol implemented at the OS level.)
I wonder if a single Nostr keypair can be used for discrete event signing (not just login) and accessed across multiple clients via PassKey? This would fill the gap…
