Honestly though I wish I could just provide my npub for 2FA everywhere. It’s so clean and so obvious. And much harder to get sim swapped. And it’s nostr so it’s sexy.
What about a nostr micro-app that worked as a plug-in for any random website to use nostr DMs for 2FA? From a technical view is that a thing that could work? I feel like if it works on Damus.io then it should function anywhere, no?
