Ghost mode! It’s really one of the awesome perks of how nostr works. This feels something that can be in @Vitor Pamplona alley.
Ok this sounds like a possible addition for nostr-login library. We could add anon mode (ghost mode?), or even sign-single-event-then-burn-nsec-mode and with account switching and other stuff we already have it should be quite user friendly. We could also auto-publish a profile event with some POW, or maybe use some ecash magic if someone smart chimes in, to get our anon event above noise thresholds.
