That's a fair point that some people are already used to interacting with a secondary app for sign-in. Though, many people still get their MFA codes via SMS and for those that have migrated to other methods, copying some numbers and pasting them from an app that has all of your accounts is still very much different and much easier than a dedicated app for Nostr for signing a wide variety of transfers transactions. If it were as simple as MFA codes, you and I wouldn't be having this conversation. It's very similar to Bitcoin except people rarely send or sign a Bitcoin transaction. Most people just HODL. We're asking people to do this potentially 1000 times a day unless they go with the fully trusted method. While similar, it's still something most don't do. Remember, we're always preaching for people to remove their coins from exchanges because that's where many people keep them. I'm not saying I know best when it comes to users and what they want, I'm just speaking from experience onboarding and educating them over the last 3 years. I may not know best, but I have a good idea on their pain points and struggles and I have a good idea on what needs to be fixed and improved to alleviate those. My goal is to take these experiences and issues and turn them into people that are able to do what they do best. Solve complex problems. Then the feedback loop should continue and these solutions should be discussed to make sure that they're still not too complicated or going to cause more problems or not solve anything at all by pushing the issue into the next bottleneck.
